I assume that "King of the North" here does not mean Scotland.

[Alucard frowns at this because actually now this is going to bother him. He knows his history, thank you very much.]

1100 would have been William II and Henry I if I remember their death dates correctly. But I'd know a moniker like the Raven King, that's distinct and borders into the night world.

[Waaaaaaaait.]

You mentioned fae?
