Overseer Drahu is a character appearing in Warrider.
Drahu can be found in Kaga, a hidden location. He is involved in a questline related to Ghouls that cannot be initiated because of Warrider's unfinished state.
Based on the game's dialogue string files, he is supposed to task the player with finding a healer that would be able to cure the Ghoul Curse.
Trivia[]
Overseer Drahu's kingdom is never stated nor mentioned, but given the fact that Kaga is located on the Swadian side of the map, it can be assumed that he is a Swadian subject.
