Nimoar

Nimoar, "the Reaver", was the leader of a human tribe of barbarians in Northwest Faerûn. The tribe was one of many to attack a small settlement on the Sword Coast North, but this attack was the one that succeeded, leading to Nimoar's tribe taking over the settlement and naming it Nimoar's Hold, but this would soon be changed to Waterdeep, the name used by sea captains docking at the harbor.

Background
Nimoar was involved in the Orcfastings War, in which the orcs from the Sword Mountains attacked and besieged Nimoar's Hold. Nimoar survived the war, but died of old age in 936 DR.
