Masut was a religious title granted to the top cleric of the Gods of Mercy religion. The exact meaning of the word has since been lost, but it is believed to have meant “a bridge to Gods” or “a friend of Gods”.

Potus Aylis was the first Masut of the Gods of Mercy and has formalized the title once in power. For decades all rulers of Loodon would need be Masuts, even if a secular title of king would also exist. Even Rondal Drofal, informally known as the First Emperor, formally held the title of Masut.
