Taninim Crusade

The Teninim Crusade was a crusade undertaken by the Imperium of Man from 678.M37 through 714.M37), to regain control of several regions lost along the north-western fringe of the Segmentum Obscurus. No fewer than eleven crusading Space Marine Chapters were sent into the forbidding region known as the Taninim Expanse that extends past the outer edge of known space. Over time, some of these Chapters that were sent to fight in the Taninim Crusade never returned.

History
In the aftermath of the Occlusiad War, the Imperium's attentions turned to regaining control of several regions lost to the Imperium along the north-western fringe of the Segmentum Obscurus. As part of this Crusade no fewer than 11 crusading Chapters were sent into the area of the Taninim Expanse in order to identify, target and destroy any emerging threats that might be found there. The expanse is a vast, alien-haunted realm that extends past the outer edge of the Segmentum Obscurus and includes such infamous and darkly fabled worlds as Naogeddon and Alaks'tar within its bounds. Over time, some of the Chapters sent to fight what was to become known as the Taninim Crusade never returned, while at least one, the Storm Callers, infamously became corrupted by Chaos and fell into civil strike between the pure of heart and the damned factions within their own ranks. The Astral Claws, however, earned great glory during their more than 40 years of crusade in the expanse, and were one of the few Chapters that passed into the region and returned again largely unscathed by the experience. Upon returning to the Imperium the Astral Claws were awarded a Sceptre of Victory at the Segmentum capital in recognition of their deeds and a temple in their honour (now deconsecrated following the infamous Badab War) was raised on the Shrine World of Pycentos to commemorate their actions.

Known Campaigns

 * Castigation of the Naraka Sub-Sector - The Astral Claws' first great campaign of the crusades was in the support of the Imperial counter-attack to regain the Naraka Sub-Sector on the very edge of the Imperium. Naraka had suffered nearly a century of brutal Ork oppression under the iron-shod boot of the Warlord Rukka Manyteef and his Bad Moons Sky-Killas. The Astral Claws took the battle to the Orks in the conflict, destroying their yellow-painted tanka-mobs on the tundra world of Gulag-VI and cutting off the greenskin's vital supplies of fuel, and later succeeded in slaughtering Manyteef's Glittanob bully-boyz on Midrash, spelling the doom of the Ork pocket empire.
 * Cythral Campaign - The Astral Claws Chapter went on to spend decades in the outer darkness of the Expanse, fighting and defeating many enemies including the outcast Eldar citadel-station of Cythral.
 * Alaks'tar Campaign - The Astral Claws battled the Xenarch Empire enclaves at the world of Alaks'tar.
 * Recovery of the Principia Gravis - The Astral Claws recovered the lost Explorator Ark Principia Gravis and returned it to [[Cypra Mundi'' to great acclaim.
