Jade. A Borogravian troll. She describes herself as naturally craggy, and doesn't see why she should polish. Jade disguised herself as a male troll, which really isn't very difficult, to join the army under the name Carborundum, and became part of the Monstrous Regiment. She met a troll she liked in Kneck Valley and, when peace came, went off with him to do more interesting things.
