Notes on specific ghosts

Victoria Valorian: Would be the most dangerous horny ghost in history if she ever found out about number 10, would definitely possess children and do depraved things, as is her sex drive has greatly diminished and her tendencies have been redirected into a stalker obsession with Anton and Marie.

Prince Tarron: Has lingered for nearly a thousand years to see through his wife's triumph over the Usurper King, may his name remain forever unremembered. Number 1 is why Syndra can talk to him, as becoming a fairy made her able to speak to ghosts, and she will have that ability for the rest of her life. Usurper King tried to exorcise him from the Palace thousands of times, to no effect
