In comparison to many, I too have not been around as long. Then again, one thing I've come to expect from Derleth is that anything can happen.
You saw the face? I did not. Might you have recognized the features? Was the face angry? Could it be the god of Derleth upset at Loki for using magic to alter the Void's sky?
I... feel normal. I'm still able to lift MjĂžlnir, but I haven't tested it nor my strength. There was no pressing need to do so. Considering how others have been affected, my guess is that I am too, but I'll need to see how much.
