Rynn's World is an Imperial Agri-World that is also the homeworld of the Crimson Fists Space Marines Chapter. It and the Rynnstar System were both named for the Imperial Reclamator Saldano Malverro Rynn who first led Imperial colonists to the system and reclaimed Rynnsworld for Mankind. The planet is sparsely populated, mountainous, and devoted to intensive agriculture. Due to its distance from other Imperial worlds and its proximity to Ork-controlled space, it is somewhat isolated from the rest of Imperium, with the closest neighbouring human planet being Badlanding. The Crimson Fists' Fortress-Monastery Arx Tyrannus has stood on Rynn's World for over a thousand years since their great Battle-Barge Rutilus Tyrannus was dismantled to build it after the Crimson Fists were granted Rynn's Wor
