Brovo, I have some questions for my character.

1. Are there already any existing reliquaries in the Papacy's capital or can I make up my own?
2. Are there archangels in the world's history and can I make one up for my character's backstory?
3. Would it count as two characters if I have a mute grave robber and the spirit of an archangel with him? The archangel's spirit is tied to his skull, which the Grave Robber carries, and he would have no physical body of his own.
4. Could you give me the name of a high-ranking member of the Papacy? They would be responsible for sending my character to the Queen's Blades, and my character biography would be in the form of them writing a letter to Kouri describing the situation with my character.
5. Are these unique traits okay?

--Trait 1. The Grave Robber's Curse: To atone for his sins, the Grave Robber is forced to do the bidding of the Papacy and carry the skull of the Archangel with him until he finds redemption. The benefit of the skull is that its holy presence staves off all forms of corruption, but separating from it means the Grave Robber's death.
--Trait 2. The Archangel's Might: Channeling the power of the Archangel, the Grave Robber can imbue his shovel with holy energy and throw it like a spear.
