The Dakaua were among the first of the Ecumene's members to encounter the belligerent Hive. After a century of war, the Dakaua discovered a twenty four thousand year-old ship that contained the proto-Hive Taox in cryo-stasis. Taox provided the Dakaua Ministry of War with vital intelligence concerning the Hive's motivations and the identities of its leaders, which the Ministry passed on to the Ecumene Crisis Council along with a recommendation to eliminate the Hive via genocide.
Some time later, after the Ecumene Council had been killed by Oryx, the Taken King at a place called the Fractal Wreath, Oryx himself asked the Dakaua to aid him in killing his sister, Xivu Arath, because he was jealous of her power. The desperate Dakaua agreed. This proved to be a trap, however, and the Dakaua were wiped out completely. Oryx's act of treachery restored his other sister, Savathûn, to life.
