I COULDN'T understand why there were two moons in the sky when I awoke, or why they were green. Groaning, I rubbed the back of a hand over my eyes, then looked again. I realized I was lying on the floor, staring up at the green eyes of a chuckling Harkat Mulds. "Have fun last night?" he asked.

"I've been poisoned," I moaned, rolling over on to my stomach, feeling as though I was on the deck of a ship during a fierce storm.

"You won't be wanting boar guts and... bat broth then?"

"Don't!" I winced, weak at the very thought of food.

"You and the others must have drained... half the mountain's supply of ale last night," Harkat remarked, helping me to my feet.

"Is there an earthquake?" I asked as he let go of me.

"No," he said, puzzled.

"Then why's the floor shaking?"

He laughed and steered me to my hammock. I'd been sleeping inside the door of our cell. I had vague memories of falling off the hammock every time I tried to get on. "I'll just sit on the floor a while," I said.

"As you wish," Harkat chortled. "Would you like some ale?"

"Go away or I'll hit you," I growled.

"Is ale no longer to your liking?"

"No!"

"That's funny. You were singing about how much you... loved it earlier. 'Ale, ale, I drink like a whale, I am the... Prince, the Prince of ale'."

"I could have you tortured," I warned him.

"Never mind," Harkat said. "The whole clan went crazy... last night. It takes a lot to get a vampire drunk, but... most managed. I've seen some wandering the tunnels, looking lik-"

"Please," I begged, "don't describe them." Harkat laughed again, pulled me to my feet and led me out of the cell, into the maze of tunnels. "Where are we going?" I asked.

"The Hall of Perta Vin Grahl. I asked Seba about cures... for hangovers - I had a feeling you'd have one - and he said... a shower usually did the trick."

"No!" I moaned. "Not the showers! Have mercy!"

Harkat took no notice of my pleas, and soon he was shoving me under the icy cold waters of the internal waterfalls in the Hall of Perta Vin Grahl. I thought my head was going to explode when the water first struck, but after a few minutes the worst of my headache had passed and my stomach had settled. By the time I was towelling myself dry, I felt a hundred times better.

We passed a green-faced Mr. Crepsley on our way back to our cell. I bid him a good evening, but he only snarled in reply.

"I'll never understand the appeal of... alcohol," Harkat said as I was dressing.

"Haven't you ever got drunk?" I replied.

"Perhaps in my past life, but not since... becoming a Little Person. I don't have taste buds, and alcohol doesn't... affect me."

"Lucky you," I muttered sourly.

Once I'd dressed, we strolled up to the Hall of Princes to see if Paris needed me, but it was largely deserted and Paris was still in his coffin.

"Let's go on a tour of the tunnels... beneath the Halls," Harkat suggested. We'd done a lot of exploring when we first came to the mountain, but it had been two or three years since we'd last gone off on an adventure.

"Don't you have work to do?" I asked.

"Yes, but..." He frowned. It took a while to get used to Harkat's expressions - it was hard to know whether someone without eyelids and a nose was frowning or grinning - but I'd learnt to read them. "It will hold. I feel strange. I need to be on the move."

"OK," I said. "Let's go walkabout."

We started in the Hall of Corza Jarn, where trainee Generals were taught how to fight. I'd spent many hours here, mastering the use of swords, knives, axes and spears. Most of the weapons were designed for adults, and were too large and cumbersome for me to master, but I'd picked up the basics.

The highest ranking tutor was a blind vampire called Vanez Blane. He'd been my Trials Master during both my Trials of Initiation. He'd lost his left eye in a fight with a lion many decades before, and lost the second six years ago in a fight with the vampaneze.

Vanez was wrestling with three young Generals. Though he was blind, he'd lost none of his sharpness, and the trio ended up flat on their backs in short order at the hands of the ginger-haired games master. "You'll have to learn to do better than that," he told them. Then, with his back to us, he said, "Hello, Darren. Greetings, Harkat Mulds."

"Hi, Vanez," we replied, not surprised that he knew who we were - vampires have very keen senses of smell and hearing.

"I heard you singing last night, Darren," Vanez said, leaving his three students to recover and regroup.

"No!" I gasped, crestfallen. I'd thought Harkat was joking about that.

"Very enlightening," Vanez smiled.

"I didn't!" I groaned. "Tell me I didn't!"

Vanez's smile spread. "I shouldn't worry. Plenty of others made asses of themselves too."

"Ale should be banned," I growled.

"Nothing wrong with ale," Vanez disagreed. "It's the ale- drinkers who need to be controlled."

We told Vanez we were going on a tour of the lower tunnels and asked if he'd like to tag along. "Not much point," he said. "I can't see anything. Besides..." Lowering his voice, he told us the three Generals he was training were due to be sent into action soon. "Between ourselves, they're as poor a trio as I've ever passed fit for duty," he sighed. Many vampires were being rushed into the field, to replace casualties in the War of the Scars. It was a contentious point among the clan - it usually took a minimum of twenty years to be declared a General of good standing - but Paris said that desperate times called for desperate measures.

Leaving Vanez, we made for the store-rooms to see Mr. Crepsley's old mentor, Seba Nile. At seven hundred, Seba was the second oldest vampire. He dressed in red like Mr. Crepsley, and spoke in the same precise way. He was wrinkled and shrunken with age, and limped badly - like Harkat - from a wound to his left leg gained in the same fight that had claimed Vanez's eye.

Seba was delighted to see us. When he heard we were going exploring, he insisted on coming with us. "There is something I wish to show you," he said.

As we left the Halls and entered the vast warren of lower connecting tunnels, I scratched my bald head with my fingernails.

"Ticks?" Seba asked.

"No," I said. "My head's been itching like mad lately. My arms and legs too, and my armpits. I think I have an allergy."

"Allergies are rare among vampires," Seba said. "Let me examine you." Luminous lichen grew along many of the walls and he was able to study me by the light of a thick patch. "Hmmm." He smiled briefly, then released me.

"What is it?" I asked.

"You are coming of age, Master Shan."

"What's that got to do with itching?"

"You will find out," he said mysteriously.

Seba kept stopping at webs to check on spiders. The old quartermaster was uncommonly fond of the eight-legged predators. He didn't keep them as pets, but he spent a lot of time studying their habits and patterns. He was able to communicate with them using his thoughts. Mr. Crepsley could too, and so could I.

"Ah!" he said eventually, stopping at a large cobweb. "Here we are." Putting his lips together, he whistled softly, and moments later a big grey spider with curious green spots scuttled down the cobweb and on to Seba's upturned hand.

"Where did that come from?" I asked, stepping forward for a closer look. It was larger than the normal mountain spiders, and different in colour.

"Do you like it?" Seba asked. "I call them Ba'Shan's spiders. I hope you do not object - the name seemed appropriate."

"Ba'Shan's spiders?" I repeated. "Why would-"

I stopped. Fourteen years ago, I'd stolen a poisonous spider from Mr. Crepsley - Madam Octa. Eight years later, I'd released her - on Seba's advice - to make a new home with the mountain spiders. Seba said she wouldn't be able to mate with the others. I hadn't seen her since I set her free, and had almost forgotten about her. But now the memory snapped into place, and I knew where this new spider had come from.

"It's one of Madam Octa's, isn't it?" I groaned.

"Yes," Seba said. "She mated with Ba'Halen's spiders. I noticed this new strain three years ago, although it is only this last year that they have multiplied. They are taking over. I think they will become the dominant mountain spider, perhaps within ten or fifteen years."

"Seba!" I snapped. "I only released Madam Octa because you told me she couldn't have offspring. Are they poisonous?"

The quartermaster shrugged. "Yes, but not as deadly as their mother. If four or five attacked together, they could kill, but not one by itself."

"What if they go on a rampage?" I yelled.

"They will not," Seba said stiffly.

"How do you know?"

"I have asked them not to. They are incredibly intelligent, like Madam Octa. They have almost the same mental abilities as rats. I am thinking of training them."

"To do what?" I laughed.

"Fight," he said darkly. "Imagine if we could send armies of trained spiders out into the world, with orders to find vampaneze and kill them."

I turned appealingly to Harkat. "Tell him he's crazy. Make him see sense."

Harkat smiled. "It sounds like a good idea... to me," he said.

"Ridiculous!" I snorted. "I'll tell Mika. He hates spiders. He'll send troops down here to stamp them out."

"Please do not," Seba said quietly. "Even if they cannot be trained, I enjoy watching them develop. Please do not rid me of one of my few remaining pleasures."

I sighed and cast my eyes to the ceiling. "OK. I won't tell Mika."

"Nor the others," he pressed. "I would be highly unpopular if word leaked."

"What do you mean?"

Seba cleared his throat guiltily. "The ticks," he muttered. "The new spiders have been feeding on ticks, so they have moved upwards to escape."

"Oh," I said, thinking of all the vampires who'd had to cut their hair and beards and shave under their arms because of the deluge of ticks. I grinned.

"Eventually the spiders will pursue the ticks to the top of the mountain and the epidemic will pass," Seba continued, "but until then I would rather nobody knew what was causing it."

I laughed. "You'd be strung up if this got out!"

"I know," he grimaced.

I promised to keep word of the spiders to myself. Then Seba headed back for the Halls - the short trip had tired him - and Harkat and me continued down the tunnels. The further we progressed, the quieter Harkat got. He seemed uneasy, but when I asked him what was wrong, he said he didn't know.

Eventually we found a tunnel which led outside. We followed it to where it opened on to the steep mountain face, and sat staring up at the evening sky. It had been months since I'd stuck my head out in the open, and more than two years since I'd slept outdoors. The air tasted fresh and welcome, but strange.

"It's cold," I noted, rubbing my hands up and down my bare arms.

"Is it?" Harkat asked. His dead grey skin only registered extreme degrees of heat or cold.

"It must be late autumn or early winter." It was hard keeping track of the seasons when you lived inside a mountain.

Harkat wasn't listening. He was scanning the forests and valleys below, as if he expected to find someone there.

I walked a short bit down the mountain. Harkat followed, then overtook me and picked up speed. "Careful," I called, but he paid no attention. Soon he was running, and I was left behind, wondering what he was playing at. "Harkat!" I yelled. "You'll trip and crack your skull if you-"

I stopped. He hadn't heard a word. Cursing, I slipped off my shoes, flexed my toes, then started after him. I tried to control my speed, but that wasn't an option on such a steep decline, and soon I was hurtling down the mountain, sending pebbles and dust scattering, yelling at the top of my lungs with excitement and terror.

Somehow we kept on our feet and reached the bottom of the mountain intact. Harkat kept running until he came to a small circle of trees, where he finally stopped and stood as though frozen. I jogged after him and came to a halt. "What... was that... about?" I gasped.

Raising his left hand, Harkat pointed towards the trees.

"What?" I asked, seeing nothing but trunks, branches and leaves.

"He's coming," Harkat hissed.

"Who?"

"The dragon master."

I stared at Harkat oddly. He looked as though he was awake, but perhaps he'd dozed off and was sleepwalking. "I think we should get you back inside," I said, taking his outstretched arm. "We'll find a fire and-"

"Hello, boys!" somebody yelled from within the circle of trees. "Are you the welcoming committee?"

Letting go of Harkat's arm, I stood beside him - now as stiff as he was - and stared again into the cluster of trees. I thought I recognized that voice - though I hoped I was wrong!

Moments later, three figures emerged from the gloom. Two were Little People, who looked almost exactly like Harkat, except they had their hoods up and moved with a stiffness which Harkat had worked out of his system during his years among the vampires. The third was a small, smiling, white-haired man, who struck more fear in me than a band of marauding vampaneze.

Mr. Tiny!

After more than six hundred years, Desmond Tiny had returned to Vampire Mountain, and I knew as he strode towards us, beaming like a rat-catcher in league with the Pied Piper of Hamlin, that his reappearance heralded nothing but trouble.
