Molten Mire

The swamp-like region of the underdark, north of the Fungal Wilds, but with slowly oozing pools and streams of magma. The rock here is often soft or brittle and travelling it is very dangerous.

Magic users from Vaahd Knulheim long ago cast protective magic over it for a year and a day to make the effects permanent, but the damage the barriers constantly sustain causes them to require frequent upkeep.
