The Grue's Cavern is a special level that appears in dNetHack, and may appear in place of Medusa's Island.
The entire level is non-teleport and shrouded in darkness, and the player must defeat the Grue lurking within to proceed.
Generation
The Grue's Cavern has two layouts, giving it a 1⁄3 chance of being generated.
Common traits
Each version of the level contains 18 candles embedded in the walls, two chunks of fossil dark, nine to 11 traps, and various random items. The candles can be worth collecting as light sources can generally be used to drive the Grue away.
Each level also includes two treasure piles. The first is the corpse of an unlucky Elvish adventurer killed by the Grue and his or her leftover equipment, including either a cloak of invisibility or a cloak of displacement. The second is a pile of loot such as might have been left behind by an unfortunate Zork adventurer: a lantern that has run out of power and a sack containing a wrathful silver elven broadsword (doubtlessly of great antiquity), a magic torch, and a platinum bar (it seems that the adventurer unwisely chose to continue relying on their lantern!).
The Grue will spawn asleep on the downstairs.

Origin
The level is derived from the classic video game Zork, which contained a Grue that would kill the player if they attempted to travel in darkness.
