Variks has us killing kells and a lot of leaders within the ranks of the fallen. Do you think variks wants control of the fallen? He seems to want to impress the queen a lot but now she's not around won't he start to feel lost for cause. If he had control do you think he'd still be an ally? Personally i do, as the fallen have wielded the travellers light already variks may know the only solution to having it back is to share it.
