Goddess of the Water Thetis

Thetis appreciates offerings of mortal sentimental value. Thetis’s essence has been contained within a Sapphire by another unknown God, likely Azathoth from this snippet of conversation:

Thetis, I implore you to submerge your palace and seal it away. I fear we are amidst a conflict upon our very pantheon. Since the fusions, your powers have not been what they used to be. I will contain your essence in this Sapphire, trusting my descendants will awaken you once more. Guide them here, help them revive you. Even if we slay him now, his descendants will seek revenge. We cannot afford to lose you, our master of water.

Thetis’s prayer states for unlocking something in her underwater temple:

Flowing healing water Divine streams of life Oh great seal I purge the darkness.
