The Separatists' Test

 is one of the sub-missions of the main mission "The Ice Palace" in ELEX.

"The Separatists are an unpredictable element in all this. If they act against me at the wrong time my plan will fail. Will they support me, or are they only interested in their own cause? I will have to win them over as allies or get rid of them completely."
