Once a marine biologist who disappeared during a diving expedition near a remote Scottish isle, she returned three years later with inexplicable abilities and an intimate knowledge of selkie lore. Claiming to have lived among the seal-folk in a realm between worlds, she joined the Seekers of the Serpent when Dr. Blackwood alone believed her extraordinary tale and recognized the potential of her unique communion with water cryptids.

The Selkie Summoner possesses a seal-skin cloak embedded with ancient runes that allows her to survive underwater for hours and communicate telepathically with aquatic creatures. Her eyes change from human to seal-like when using her abilities, and she can create haunting vocalizations that resonate at frequencies known to attract cryptids from the deepest waters. Each summoning drains her physically, leaving temporary gill-like markings on her neck that fade after several days of recovery.

She serves as the Seekers' primary conduit to the underwater world, leading dangerous rituals at the water's edge during critical moments in the search for Nessie, and translating cryptic messages from lesser water cryptids that point toward the ultimate truth of Loch Ness's darkest secrets.
