[@Mugin] Hey there, Mugin, thanks for showing interest and posting a character :) 

Looking over Calvin, he looks to be a pretty good character with a solid background and formatting. One thing I felt necessary to bring up however is that, while Thanatos is listed as [i]having[/i] Necromancy, the purpose surrounding his job is to [i]reap[/i] the souls of the dead, and ensure the Doors of Death remain closed, thus separating the real world from the Underworld. 

That being said, after some deliberation, Calvin can keep Necromancy as a power - but with the effect that using it [i]probably[/i] won't make Thanatos too happy, given Calvin is effectively reducing his work XD

All that aside, I don't see any reason why he shouldn't be accepted! Welcome to the roleplay, and feel free to get an intro post up at anytime :) Also, don't forget to try and add pre-made characters to his Relationship section, that way there's a bit of a fleshed-out guide to how he interacts with the other campers.
