You have plunged into a pact with the deeps. An entity of the ocean, the Elemental Plane of Water, or another otherworldly sea now allows you to draw on its thalassic power. Is it merely using you to learn about terrestrial realms, or does it want you to open cosmic floodgates and drown the world?

Perhaps you were born into a generational cult that venerates the Fathomless and its spawn. Or you might have been shipwrecked and on the brink of drowning when your patron’s grasp offered you a chance at life. Whatever the reason for your pact, the sea and its unknown depths call to you.

Entities of the deep that might empower a warlock include krakens, ancient water elementals, godlike hallucinations dreamed into being by kuo-toa, merfolk demigods, and sea hag covens.
