{{ :cavern_perch_gg_scenic_2d.png?200|}}


===== Overview =====

The Cavern Perch is a large, deep-dwelling freshwater predator endemic to the underwater cave networks of [[lake_orlanda|Lake Orlanda]] in the [[asari|Asari Region]] of the [[habitual_belt|Habitual Belt]] on [[the_planet_voi_700_d|VOI 700 D]]. It is adapted to the pitch-dark conditions of submerged rock systems and rarely ventures into open water. Feared by local fishers and respected by the [[the_orlanda|Orlanda Tribe]], the Cavern Perch is known for its patience, ambush tactics, and massive bite.

The Orlanda refer to it as "Mur'Thaal", meaning "Watcher in the Stone," and believe it to be the guardian of hidden truths in the lake's depths.
