Ulgulu

Ulgulu was a barghest whelp from the plains of Gehenna. Sent to the Material Plane to eat and grow, he and his brother Kempfana made their home in the cave of the hill giant Lagerbottoms, which they used as a base from which they could safely mature before returning.

When a group of their gnolls, main force for capturing humans for devouring to mature, sent to retrieve a pair of farmers from the Thistledown farm never returned, he and his brother]] sent their quickling ally, Tephanis, to discover what had happened. When Tephanis returned and told them that the newly-surfaced Drizzt Do'Urden had slain the goblins, they had the quickling steal one of Drizzt's scimitars. Ulgulu used his shape-changing abilities to make himself appear as a drow, and with Drizzt's scimitar, attacked the Thistledown farm. After slaying the residents, he left the broken scimitar so as to make people believe that Drizzt had killed the family.

When Drizzt learned what had happened, he and Guenhwyvar attacked the cave's inhabitants, destroying the two barghests and many of their goblin allies.
