[@BladeSS4] There are still several issues with this application as is, but it's somewhat more workable than before.

[list][*]We already have another player whose magic is Sun themed, as well as an important NPC, so I feel like this would be a little too much overlap given the rarity/power of that element.
[*]I'm not going to allow the grimoire to have a spirit inside it.
[*]Given his background information and the fact that he's not going to have lived multiple lifetimes anymore (you'll need to correct that in his details btw), it doesn't make sense for him to be a master martial artist. Characters starting the game shouldn't really have something like "knowledge of many styles" and so forth.
[*]The "creative use of mana" skill sounds like more of an informed trait, it's not really something that differentiates him from other players in any noticeable way. Especially when his spells are just "flashbang" and "fireball" respectively.
[*]This is more of an opinion than something that goes against "the rules," but to be perfectly honest a lot of details in his background, personality, and description of his magic come across as very...Gary Stu/Main Character Syndrome. I think characters having tragedy or extreme events in their lives that drive them is fine, but this just doesn't come off that well.[/list]

Again, it's more malleable than it was before, but by the time all of the above was addressed I feel like it would still be a completely different character.

EDIT:
I will be working on a GM update post this weekend! I think everyone's pretty much done with collabs, right? If not, let me know!
