As an ice troll, Galtroppa is a humanoid giant of wintry coloration. Overall her kind looks quite human, with long tapering noses, large round ears, and gigantic lower canines that jut from the mouth like boar tusks. Troll females tend to be far less ugly than their male counterparts, so Galtroppa could pass as pretty to someone with lenient tastes. Her nose is shorter than most, and her tusks grow in perfect crescent curves. Her leathery skin is a pale, icy blue, and her white hair is kept bound in two thick braids at her back. Her eyes are small and suspicious, the color of a blue winter sky. Her clothing is made of animal furs held together with heavy stitches, forming a tunic-and-shorts ensemble that exist only for the purposes of modesty, since ice trolls are unaffected by the cold. Her feet are always bare.

Galtroppa is the undisputed leader among her siblings -- or at least, she smacks her brothers around with enough force that they know they'd lose if they ever did dispute her in more than grumbles. She is confident and knows how to get what she wants: by subduing others into doing it for her, because that reminds them who's boss at the same time that it saves her having to do the hardest part of a job, herself. She's not lazy, but she understands that if you're the kind of person who rules by force, you only stay in charge as long as your underlings remember just how forceful you can be.

Despite her gruff and overbearing demeanor, Galtroppa has a strong sense of pride and loyalty. She would never abandon her brothers or make them do something dangerous enough to possibly get them killed. When she makes a promise, she keeps it, and she makes sure others keep their promises as well -- by beating them around the head, if she has to.
