[@Happy Go Lucky] Hence why I said it probably will not end up being relevant at all. I just worry unnecessarily. A lot. :)

I really just mean details and minor stuff. For example, if I say a spell goes wrong in such a way that in your lore should not happen, are you cool with that? Or, if one of my NPCs can magically sense that he has a demon heart, and in your world this shouldn't be possible, will you accept that?

Sorry, I didn't write what I mean clearly. I won't touch his plot or attempt to NPC any of the other characters mentioned in his backstory, and I have no intention of taking the RP to his world. That is totally yours and off-limits. I'm only talking about technicalities. :)
