Hold the fucking phone.
The King is Viscount?
The fuck? The rank of Viscount is so far below the rank of King it isn't even funny. Is Viscount even a landed title? At most it can only hold land at Baron level... like a castle and surrounding villages or whatever.
And sure, a King could hold lower landed titles, but you don't get to be a King with a single county or less. Even a Petty Kingdom or Principality requires a Duke-tier title, surely?
A proper King level title requires a Kingdom of multiple Duchies, each of which contains multiple Counties.
Just what is with the noble ranking system in this narrative?
