The Time Variance Authority has lots of Infinity Stones as shown in the first episode. The implication, if memory serves, was that Infinity Stones have no power in the TVA HQ.
Why is this?
As I understand it, Infinity Stones aren't supposed to have power outside of the universe in which they exist. The only reason they had power over Dormammu is that his universe and ours were connected for a bit. Maybe the TVA exists in an alternate universe?
