You are at the entrance to a large stone hut, filled with a huge assortment of various items. Shards of pottery, wands, flasks, knives, skulls, swords, and everything else imaginable are jumbled together in huge, awkward heaps.
The tunnel twists and turns, climbs and falls. After one of the drops, you realize you can't get back up. Pressing onward, you eventually emerge...
You crawl down the shaft, and eventually drop through a hole in the ceiling of a cave below. Unfortunately, you now have no way back up.
There are lots and lots of bones in this grim, ash-filled room. They look like they belonged to humans, but there isn't anything left to help you figure out who they were, what killed them, or why. The bones have teeth-marks, for what it's worth.
This small back room has rough runes sketched into the floor. They were not competently drawn - they're powerful enough to aid in summoning diabolical creature, but not enough to contain them. In other words, they're as badly done as possible.
Among the scrolls filled with deranged ravings, you find a genuine spellbook! The rituals it describes are not complicated, and you can digest them very quickly. You now know the spell Wall of Force.
Among the scrolls filled with deranged ravings, you find a genuine spellbook! Unfortunately, you don't have a sufficient grasp of mage lore to understand it.
This bookshelf is disappointing. It's filled with crude lichen paper scrolls, covered with the inane or bizarre scribblings of the mages that lived here. They were fascinated with the idea of summoning demons. You doubt they were that competent.
You cross another narrow stone bridge connecting the stone spires. This time, you notice the stone is fragile. In fact, it's crumbling under you! You start to turn back, but realize that behind you is where the stone is crumbling! So you jump forward...
Monsters climb out of the chasm and drop from the ceiling simultaneously. You must smell very appetizing.
Monsters suddenly slither and scuttle out out crevices in the floor. You're the best opportunity for a meal they've had in a long time.
Suddenly, a swarm of bats flys up from the chasm below you! They rise, bank around, and swoop down, aiming for you hungrily.
You find a small portal, flickering and freshly created. It may not be here long - you step into it while you have the chance. Vertigo seizes you. Then, you find yourself...
Suddenly, the room is filled with whirling blades!
You pull the lever. Nothing happens, or, at least, nothing you can detect.
You move away from the book. There's no telling what could be unleashed from doing something to or with a book of its power.
The tome is incredibly old, and extremely disturbing. Each page is a sheet of demonskin, describing some sort of horrible ritual for the summoning and binding of diabolical creatures.
You jump forward, athame first. The rune flares white hot, and sends a wave of heat at you. The athame scrapes across the sigil, defacing it. Its magic fades, but not before you receive serious burns.
The moment you step near this rune, it throws a searing blast of energy towards you. You manage to get past it, but not before taking serious damage.
