Keeper of the Deep

Keepers of the Deep are a variant of Hive Ogres employed by the Lucent Brood to defend the Lucent Hive ship they crashed into Titan's methane sea from the Guardian fireteam infiltrating it.

Gameplay
Major Keepers of the Deep are a crucial part of the fight against Ecthar, the Shield of Savathûn. After a trio of Blistered Knights are slain, a Keeper will appear near the central statue. Slaying this Ogre will reveal a deepsight cloud near the fountain in the center of the room, which allows players to see the runes inscribed on the walls to the left and right. Ecthar will also dive into the methane below and activate his Sentinel Shields to hunt any submerged Guardians.

The Ultra variant bars the fireteam's way to the final fight, though it has no special mechanics and can be quickly dispatched.
