Brinkt was a happy goblin, second wife of Chief Ripnugget posessor of most of the love of the leader and the good gifts of new and interesting things. Her happiness was taken away as the chief's harem grew and Bruthazmus moved in. Brinkt does not share well. If anything Brinkt was certain that she deserved many husbands, she was more than enough for Ripnugget and Bruthazmus all on her own without all the other women in the way.
Brinkt exploded. Really exploded. The goblin woman's arcane talents came to the fore in a fit of squealing anger and ever since she's been taking whatever she wants determined to be one of the dominant personalities of the tribe. She still fights with Ripnugget over what sould be her place in the tribe and her 'status' is utterly in flux but she's no longer with the harem.
