He was part of the circle of knowing, right? I found it so weird that he wasn't in the CGI either praying, or with Louisoux as normal. While SE completely forgetting about Atomos would suggest that they forgot about him, I'm unsure whether they have or whether his absence from the final cutscene is tied to the confirmed news that Louisoux will be in ARR.

Creepyguy buffing people in towns and attacking passerby adventurers with piestes/wolves/raptors in ARR? Yes please.
