Just to precise: I didn't mean it as a bad thing for the "PvP" part. Direct confrontation PvP is often bad/hard to run if it's not the direct goal of the adventure; But here it would be more moral differences, since the actions of players towards chaos or order have a much more important impact there than in other more mundane adventure. That might lead to indirect opposition but without animosity, especially since the two champions (and other characters) both seem pretty decent people and are not really at odds with each other outside of their cosmological role. That is a very good scenario in my opinion to remind players that order vs chaos is NOT the same line of moral dilemma than Good vs Evil, and that it requires a much more nuanced take with more balanced results in the end.
