Couldn't "daario" be "queen's" or "king's"?
"Queen's" in nominative is "Dārī" and "King's" in nominative is "Dāryssy". In genitive they would be "Dārȳti" and "Dāroti"
I think he means in singular number. So I believe it would be dāro king's and dārio queen's
Ah yes I misunderstood. The apostrophe + s should indicate the genitive and not the plural. Sorry :D
