I’m not going to dump all of the info seeing as it will be widely available to us tomorrow, but I did think it was interesting that the Scarlets seem to be like super cockroaches. They not only endure, they come back with some bite to them.
They’ve taken a foothold on Fenris Isle, though I fully expect that will be dealt with by the end of the quest chain.
Also the Forsaken haven’t lost their love of Blight.
