A sturdy merrow of great intelligence and force of presence, the Patroness’ scales are an abyssal black highlighted with corpse blue. Like most of her kin, the Patroness’ head resembles a predatory fish, though with a hint of almost elven-like beauty. Her body has been augmented by dark magic over the years adding a pair of thick, tentacles, a crown of spined urchins, and a chin that expands like a toad. These additions allow the Patroness extraordinary powers stolen from sea beasts, but her potent magics remind her greatest asset.

The Patroness likes to strike bargains and curry favors, especially ones with tragic, twisted endings for the other party. This instinct comes from her magic mentors, a trio of hags she killed and devoured some time ago. The Patroness would like to think they would be proud of her for doing that. Haunting coastal waters, she offers deals to merfolk, merrow, and water breathers alike. Some seek her out for hidden treasures or safe passage on the waters. Others want to bring a loved one back to life. With each bargain struck comes a damning geas where the souls of those tormented fuel the Patroness’ young and twisted beauty.
