The Brazen Coalition was formed by sailors who fled across the sea, escaping the final advance of the Legion of Dusk against the Free Cities of Torrezon. These mariners originally sought to establish colonies on Ixalan and trade with the cities of the Sun Empire. But when the Sun Empire drove them off, they turned instead to piracy and plunder. The Brazen Coalition has since become a loosely affiliated group of pirate captains who seek to rule the seas and claim the riches of Ixalan—especially the Immortal Sun.
