Gelihast

Gelihast is a level 25 elite murloc mini-boss in the Pool of Ask'ar of Blackfathom Deeps. He goes down quite quickly but he can interrupt and kill casters very quickly, dealing high damage as he is wielding 2 swords and has an incredible attack speed. Killing him allows access to an altar, when used it gives the beneficial debuff Blessing of Blackfathom. Warriors can kill him in a few seconds with Retaliation and a 2-handed weapon. Gelihast is in a large room filled with Blindlight Murlocs, and it is not uncommon for a fleeing Murloc to pull him into the fight causing a wipe.

He is killed by Subjugator Kor'ul, who then takes control of his murlocs. Like Lady Sarevess, his body is still found on its sacrificial altar.

Adventure Guide
''The Old Gods called, and Gelihast answered, forcing his way into Blackfathom Deeps and slaughtering nearly a dozen surprised Twilight's Hammer cultists with his twin swords. Impressed by his ferocity and brutality, the cult allowed him to stay, and he built his own shrine to offer sacrifices and receive blessings from the ominous presence in the temple ruins.''
