First, it was the Odin FATE that became a trial in ARR, then it was Proto Ultima in Dun Scaith in HW, and now that SB is out, which FATE do you think might become or be part of an instance this time? My guess is the giant fox from the Foxy Lady FATE. Probably wouldn't make sense for Ixion to be one since we already get him as a mount once we get 12 tokens.
