[@Dead Cruiser]: While I did say I was fine with the idea, there's some details that you might have to tweak. Firstly, she wouldn't be the oldest vampire in existence(though probably the oldest one to appear in the RP since the second isn't as old.) though she'd still be old, certainly. Another thing of note is that vampires in this setting do not traditionally have transformation capabilities or the ability to drain magical energy through a bite(the latter is only draining blood, not mana), though it could probably be justified by mana passing through blood, which is a fact of the setting.

Sorry, this is something I've worked on for years and it's hard to include every detail in the OP. ^^;

As a side comment, demons are very much a thing in-setting(though not playable for this RP) and a sword to kill them makes sense and would not be the only thing designed in that manner.

[@SilverDawn]: Aryu seems fine, accepted.

[@shadowsaint007]: The one who makes the most sense magically is probably your first idea. Your third does as well, but the Catholic Church's influence and involvement is a semi-major thing in the RP's setting. I was considering editing the OP to include them but I'm worried about taking away from the magi's numbers if I make them playable. After all, the magi are supposed to be the most numerous group in the RP due to the ritual's purpose and nature.

[@The Omnipotent Sphere]: The Twenty-One Circles of the Major Arcana are the twenty-one "Big" Mage Circles, all named for one of the major arcana tarot cards. For example, there's the Tower in London, and the Moon in Japan.

As a general note, this is a setting I've worked on for years and there's too much information to put in the OP. If you have any questions about anything, please, please feel free to ask.
