The Quest is still important to the quest, and I'm not sure why you don't trust
@PoptartProdigy to ensure the "contamination" is minimal. Yes, there are things that have been revealed in the RP that the Quest doesn't know yet.
That's okay.
They're telling different stories. It's not "locked" from the Quest; I'm sure it's entirely possible to discover all of that information in due time. Especially since Kakara's a Seer.
As for the being you're referring to, there are downsides to that, and it's explicitly an alternate version, albeit one that demonstrates at least some of what's
possible for Kakara far enough down the road.
As for the "issues with the RP", go take it up in the RP thread or in PMs with Fourth/Poptart?
