It is not clear how exactly it occurred, but this drawing shows Grand being driven out of the planet Vile during its conquest. The note received from Keinding said specifically "Vile: Grandians defeated by unknown forces." . The green and red Vileans appear to be using some sort of ability to drive the Grandians out, they even redirect a laser into Grandian spaceships in the back ground. The reason why the two Grandians in view are in the air upsidown is because the Vileans are forcing them to do that. They even have an entire Grandian ship in their control with an aura shaped like another Vilean to throw the Grandians off (it looks like a brown stick figure in the back ground). We think this may be some kind of magical projection ability. Grand of course had to evacuate and leave Vile.
