Talasa System

The Talasa System is an Imperial star system located in the Realm of Ultramar in the Ultima Sector of the Segmentum Ultima.

Talasa Prime was granted in perpetuity to the Deathwatch by the Ultramarines.

Notable Worlds[]

The worlds of the Talasa System, in order from those that orbit closest to their star to those that are the farthest away, include:

Talasa Prime (Fortress World) / (Deathwatch Watch Fortress) - Talasa Prime has been gifted in perpetuity to the Ordo Xenos of the Inquisition and the Deathwatch Chapter by the Ultramarines. It now serves as the foremost watch fortress of the Deathwatch and one of the primary training centres for that Chamber Militant of the Ordo Xenos. Talasa Prime, the archetypal training world for the Deathwatch, maintains an Aquila pattern watch fortress in addition to dozens of attendant watch stations. It has a wide variety of kill-teams, each tested against those xenos races that would encroach upon Ultramar's borders. Overall command of the watch fortress as watch commander is entrusted to Watch Master Mordelai, a humourless and extremely efficient proponent of the Malleus war doctrine, who has the long-standing trust of Chapter Master Marneus Calgar of the Ultramarines himself. Like most watch fortresses, Talasa Prime maintains five Watch Companies, numbered Primus to Quintus, comprised of four kill-teams of varying types each.

Talasa Secundus (War World) / (Hive World) - Talasa Secundus is the most heavily populated world in the Talasa System, home to many hive cities. During the 13th Black Crusade, Talasa Secundus was one of the many worlds of Ultramar that were invaded by the Chaos forces under the command of Abaddon the Despoiler. The planet was again assaulted during the Plague Wars of the Era Indomitus, this time by the Heretic Astartes of the Death Guard. The Chapters of the Silver Templars and the Novamarines engaged in a fierce battle to liberate the world from the mortal and Daemonic servants of Nurgle.
