Hades

From Linkrealms

Hades, the home of Hell Spawn, is an arena-style phase Dungeon that was previously the only place to find many Monsters. It is one of the oldest dungeons in-game and holds a record for being put together in a single night.

Hades is currently the only place in-game to find Darklings.

For information on the monsters of Hades, see the Bestiary.
