Parun is a title given to the ten signatories of the Guildpact and essential founders of the modern-day guilds. In order to bring about a semblance of order and cooperation on ancient Ravnica, the paruns took part in the creation of the Guildpact to ensure their factions had a role and purpose in this new world order. Some of the paruns yet exist today, still leading their guilds ten millennia after signing the Guildpact.
