Adrianna

Adrianna was a fetchling from the Shadowplane, or the Netherworld, who had been born during the Age of Collapse on the other side of the planar barrier. Not much is known about the early life of Adrianna nor the Shadowplane during this time, as Adrianna was a rather private person to the Harbor of Hearts, but it was known that she had a wife named Wren and some version of a happy life in the Shadowplane.

The Alchemist Mathesis pulled Adrianna from the Shadowplane as part of a series of experiments with the planar barrier, and didn't bother to kill the Fletchling, allowing the eventual escape of Adrianna to Moonlit Village. It was here that Adrianna founded the Harbor of Hearts adventuring guild with the ulterior motive of eventually finding a way to return back to the Shadowplane to reunite with her wife. 

Adrianna was a distant guild-leader, but did guide the Marked adventurers all the way to the Second Hero's March, where she participated in the final battle with Mathesis, assisting in Mathesis's defeat. Adrianna immediately took the Goddess Atropos's offer of a one-way teleport past the planar boundary, and reunited with her Wife on the day of the Ascension of the Worldweep. Nothing further is known about Adrianna due to communications between planes still being impossible in the Age of Renewal.
