Aldones is the name of the first King of Yhtill. It seems that kings in Yhtill also take this name when they become its ruler.

On the night Aldones announced his dynasty over Yhtill he 'found The Yellow Sign'. What this means is unknown, but it seems to be a sore topic in Yhtill.

Umberto uses the name Aldones when dealing with Julian Knight in order to catch the interest of, and thereby verify the identities of, the other investigators on board the Viceroy of India.
