The great volcano in the Lava Molt split wide open and poured out floods of lava when the Abrominae stirred within his prison.
A careful adventurer can still pick his or her way among the ruined shards.
The obsidian bridge leads, after a few turns, right to the base of the volcano. A series of cleared paths through the rubble head up the slope. Glass paths lead into the heart of the ruined volcano. Beneath the glass you can see rivers of lava. Skeletons pole strange enchanted rafts up and down these rivers.
