Umentu was the Head Cleric of the First Bastion, a temple to Erathis in Westruun, Tal'Dorei. In 812 PD, a massive, seemingly bottomless sinkhole emerged beneath the temple, taking a portion of it into the city's Underwalk Ward. After initial investigators went missing, Umentu sought the aid of courageous, able-bodied mercenaries to venture inside in search of answers.[1]
