Oh come on.
DUNGEON 1
A large hole is open in the ground in CUSPIA. People have been sent down to look but no-one returned. As soon as you venture down, you land in a puddle of quicksand. A tree with a long branch hangs out over the puddle. The next room is reached by crawling through a small tunnel.
In the next room, there are Desert Bats that swoop at you and fly past to reach the great outdoors. There is a giant chasm with quicksand surrounding a platform in the middle. Monsters come out of the quicksand and start attacking you for invading their territory. When they are all disposed of, a large staircase emerges out of the quicksand and rocks crumble away to reveal a hole in the wall, near the top of the chasm. However, sand remains on the stairs as they emerged from the quicksand. The top must be reached without slipping.
(PUZZLE ROOM) (Above picture)
Once you pass the puzzle room, you emerge into a series of long, dark corridors in which monsters reside. The heat increases as you go deeper in and the corridors never seem to end. However, they do end at a massive door which leads into a sanctum where you pick up THE FIRST KEY and A PLOT ITEM.
