From the Living Greyhawk Journal #5:
"The ursine figure is in fact a guardinal, a normally chaotic good outsider dedicated to contemplative philosophical pursuits. In late 591 CY, a group of adventurers from Safeton known as the Crimson Cadre sold the creature to the arena for a pretty penny, claiming to have captured it in an expedition to the Pomarj. In fact, the beast’s name is Abulax the Even-Handed. Captured by the cadre after he foiled their attempt to unleash the demon lady Ahrimanes to assist the forces of Turrosh Mak, the creature now suffers under a powerful magical compulsion. Abulax outwardly revels in his new destructive role while inwardly seething with rage at his current status. If released from his ordeal he might be able to point his benefactors in the direction of the Crimson Cadre, who no doubt plan to renew their demonic quest."
I knew I remembered seeing a reference to Ahrimanes as a "demon lady" somewhere. So, anyway, previously neglected Ahrimanes fluff.
