To Prince Consort Lorenzo Dolore

Dear Prince-Consort Lorenzo Dolore,
My name and title given to me by my father is Volatia Oleander, Princess of Crypha, the Divine Vessel. The latter part is what I require your help with. Princess Illara has told me that you are experienced with the sort of problem I am having now.
Please find the enclosed drawings, they are but a small sample from the multitudes covering my skin. I must know what the runes on my body mean and how I can use them to dethrone my father. When I consulted Prince Cassander about them, he was able to read three words: Tool, Vessel, Champion. When the royal archivist of Athanor, Pandora Silver, was studying them she said that they were not magic but a formula.
I know you are worried about the Crown Princess, your nephew, and your niece, and I swear to you now that I will protect them with my life.
Sincerely,
Volatia Oleander
