This is a gigantic, open-aired chamber, filled with bubbling lava and

a multitude of rocky islands. The obsidian walls tower above you,

their sheer faces smooth and without handholds. The heat in this area

is intense, and the air shimmers in waves all about you. A massive

island in the exact centre of the lava contains what appears to be the

lair of some large beast. In the middle of the island is a pulsating

ruby. A lava tube leads south, and a crack is in the northeast wall.
