Wilhelmina Kaas
From For Companion and Country
40, human female, built like a lumberjack, is a mercenary, carries a longsword. Notable for being one of the only members of the refugee caravan who was armed. Wilhelmina found herself outside the city the Baert/Krol group and came along with them as a guard; she was the group's only guard until the party decided to escort them to Baldur's Gate.
Presumably Wilhelmina is staying at the Elfsong Tavern with everyone else due to the party's deputization into the Flaming Fist.
