Gasterclaw

Ysolda of Grizzlemaw was a powerful warrior, who, despite her military prowess was forced out of her home in Grizzly Hills by the maddened Furbolgs. In her desperation, she traveled south to Gilneas, and married Gareth Bayne, in order to build up her forces and retake her homeland. She had one son, Sir Aemon Bayne.

Ysolda was descended a long line of humans that interbred with Vrykul.

History
Prior to Yowler, the mighty Gasterclaw was the undisputed leader of the Gnollish Redridge Clan. Gasterclaw was immense and brawny, and used his brute force to lead raids deep into human territory. Naturally, the Black Dragon Darkblaze saw an ally in the brute while plotting the destruction of Lakeshire. Diplomacy, however, was not a matter of concern to the beast, who saw fit to immediately charge into combat against the dark wizard. Darkblaze quickly cast a shrinking curse on the gnoll, rendering him virtually harmless, after which he was sent to Nefarion as a gift.

Aemon and Gasterclaw were both kept a for pit-fighting in Blackwing Descent. Although, the tiny gnoll was designated to fight small animals and such by Nefarion, who happened to be an aspiring Pet-Battler in his free time. Aemon snatched Gasterclaw from his cage during his escape from the Black Dragon's lair. Since then, the warrior has kept him around for pet battling, and perhaps to fetch things from small places if circumstance demands.
