Due to his "imposter" being in the event, does this mean that Raezon will be coming back? Or was the imposter included for the sake of having a complete pantheon?

*crosses fingers*

There were also Shikari imposters, etc. I wouldn't be TOO hopeful, but maybe!

There were impostors of all of most, if not all of the Divine who've ever been in the realms (aside from Hajamin who, sadly, has been eaten). This might be a chance to rearrange some, but I doubt most of them will be back.

Stick with MOST because I didn't see an Isune anywhere.

I think Tully said he saw one. Could be making that up though.

Saw them a lot. They were all over the highways.

I have yet to see Isune in real life, in game. (let alone an imposter Isune)
Wow that sounded weird.

You may not have, but a few people died to imposter-Isunes.

If they have a current fulcrux there was an imposter. It was explained in the event ending.
