unsuspected smaller rents in the walls and ceiling, and I was hard put to avoid them all.

From outside came sounds of a kind I couldn't place or recognise. They reminded me most of birds made of machinery, and the sound grated on my nerves like fingernails on the blackboard of my soul. The exterior atmosphere began seeping in through the jagged steel rent, driven by the greater pressure outside. It smelled like crushed nettles, thick and choking. It burned inside my mouth and nose, and I backed away from the crack in the wall, fighting an urge to vomit. I yelled for the train to go faster and curled up in a ball on the floor.

We left that place for somewhere else, and slowly the poison in the air diminished, left behind with the awful trip-hammer songs of mechanical birds. New air built up, flat and stale, from the carriage's reserves. I gulped it down anyway and slowly uncurled from my protective ball. My hands and face were still smarting from their brief exposure to the fierce light. I sank down onto the nearest seat, slumped and almost boneless. Too much was happening too quickly, even for me, with never a chance to rest. So tired… I think I'd have sold my soul for a good night's sleep.

Luckily, no-one was listening.

I looked up sharply as the quality of air in the carriage suddenly improved. Light from a bright summer's day came flooding in through the jagged rent in the wall, bringing with it new sweet air, rich in oxygen. It was hot and humid, thick with perfume, like the crushed petals of a thousand different flowers. The extra oxygen made me feel light-headed, and I grinned stupidly as I took in one deep breath after another. I got up and wandered over to the rent in the carriage wall, and that was when a hundred heavy vines with barbed thorns thrust their way into the carriage from outside. Decorated here and there with thick pulpy flowers like sucking mouths, they lashed around, thrashing and coiling with dreadful energy.

More and more of the vines forced their way in, twisting around each other, flailing back and forth in the confined space, taking up more and more of the carriage while I backed cautiously away. My feet made a scuffing sound on the grilled floor, and immediately every vine reached out in my direction. The flowered mouths screamed shrilly, a vile hungry sound. I cut at the nearest vine with the Kandarian sacrificial dagger Cathy gave me for my last birthday, and the slender blade sheared right through the vine, thorns and all. All the flowered mouths howled with rage and pain. The severed vine bled a clear oozing sap, and the stumpy end just kept coming after me. Half the carriage was full of the roiling, thrashing vines now, and more were forcing their way in, widening the steel rent in the process.

I slashed open one of the leather seats with my dagger, pulled out a handful of stuffing, and set fire to it with a basic elemental spell I normally only use for lighting friends' cigarettes. The stuffing flared up eagerly, yellow flames leaping high in the oxygen-rich air. I tossed the blazing mass into the midst of the crashing vines, and a dozen caught alight all at once. The pulpy flower mouths screamed in unison as the fire spread quickly through the vegetable mass. All the untouched vines whipped back out the rent, leaving the others to burn and die. The flowers howled like damned souls as they burned.

Thick black smoke filled the carriage. The vines and flowers were all dead, but they'd spread the fire to the carriage seats. The train screamed through its hidden speakers as flames took hold of the carriage. I yelled back at the train to keep going, then had to break off as a harsh coughing fit from the smoke took hold of me. I backed away from the growing inferno and crouched on the floor where the air was still clearest. Thick tears ran down my face from my smarting eyes. I couldn't see anything, but I could hear the roar of the fire drawing closer.

And then the whole carriage shook and shuddered as the train ground to a sudden halt. The carriage door cracked itself open, a few inches at a time, while I crawled towards it on my hands and knees. I forced the door open the last of the way
