Vacu

The Vacu were a group of human preists that, according to legend, served the higher demon lords of Gielinor during God Wars. They are referred to frequently during the Legends' Quest, during which the Karamjan shaman Ungadulu sheds some light on this history and nature.

According to Ungadulu, the Vacu served demon-kind at some point in the past. Given that the demon Nezikchened refers to the player as Vacu, and is believed to have been imprisoned in the Kharazi Jungle during the God Wars, this was likely their time of activity. Little is known about the Vacu themselves. Many demons left the Infernal Dimensions for Gielinor to serve Zaros and, later Zamorak; given that so many demon lords were active at the time, it is highly likely that the Vacu's role in Gielinor was fairly large.
