Brine Pact Warlock

From publisher blurb: "Some say the sea calls to them. You called to the sea and something in it answered." Brine Pact Warlocks call upon the might and mystery of the depths of the ocean. With an aquatic theme, Brine Pact Warlocks can bring the crushing, frigid depths of the ocean to bear against their foes. The only question is: What answered you and what does it want in return?
