Uk'otoa

 is a leviathan imprisoned under the Lucidian Ocean. As an NPC, is played by Matthew Mercer.

Appearance
Legend says that Uk'otoa is a large serpent-like creature with many eyes along their body. On the altar above Captain Avantika's door aboard the Squall-Eater, they are represented by an ouroboros with nine eyes over its body.

Background
Uk'otoa is a creation of Zehir, the Cloaked Serpent, left to rule the entirety of the Lucidian Ocean as his proxy after he was banished during the Calamity.

The Ki'Nau of the Swavain Islands were granted the blessings of Uk'otoa. Captain Avantika expressed that, with this blessing, "nothing and no one could stand before them." However, the surviving worshipers of the Cloaked Serpent grew jealous, sealing Uk'otoa beneath the depths of the Lucidian Ocean and defaced the temples built in their name.
