Following the events on Volia, the Aschen started dialing the list of Stargate addresses given to them by Colonel Jack O'Neill in their plan for galactic conquest. The first planet they dialed was being consumed by a black hole and as a result, Mollem and several of the Aschen leaders were killed. In retaliation, the Aschen tasked scientist Mirris, who was also Mollem's wife, to come up with a bioweapon to wipe out the Tau'ri.
