deadpixel, I like the sheet but there are just two suggestions I have. I wouldn't recommend having a crippled character as this roleplay stretches across nations and even with magic he would be particularly vulnerable in a fight. He could have a gimp leg but I don't think him being fully disabled like that would be very fun to play. Of course he could always have a special enchanted limb or two. 

Also, this wasn't in the intro but like any magic system necromancy is usually looked down upon by other mages as forbidden magic. He can still be one but in secret otherwise he'd be under intense scrutiny even more than as a crippled magical foreigner. I reccomend he have another practice he's skilled in addition to necromancy. Other than that the sheet looks good.

Dead Cruiser, thank you I think world building is great and the best way to do that is collaboration. Well you actually gave me the idea of aquatic dragonblood so I came up with House Seafire, more aquatic Draconians who ride sea serpents. If that is what you meant by your question.

Barioth, its a very well written sheet but I think you could do to add more paragraph spacing. The main issue is that Orpheus in his story is dead and we can't play zombies in the rp :p However this character could be related to Orpheus somehow, maybe a relative or someone who inherited his lyre. You could keep the sheet the same but just have his lyre be inherited from Orpheus insttead of him being Orpheus. Or there might be other musicians in story you could draw from.
