Shadow Leech Hive

The Shadow Leech Hive stored Shadow Leeches for use by the Makuta in Karda Nui. The hive was guarded by Mutran and his lab assistant Vican, who also bred the Shadow leeches. At one point, Kirop inadvertently led the Toa Nuva to the hive. The Toa managed to destroy some of the vats before it was destroyed when Toa Ignika killed the sentient stone cord holding the structure up, sending it hurtling into the swamp.
