The Ratmerchants' Guild of Anak is one of the most prosperous and powerful organizations in all of Kaiantor, made up of Anak's wealthiest merchants, including Lord Montrigo Agrapulia, who is Guildmaster, and his son Seviglio.

Only rats can join the Guild, though it does accept foreign mercenaries as guards in order for their hired muscle to appear more exotic and intimidating to the average person.

They have a guild hall in Aiitz as well.
