==History==
Discovered by the [[Expedition Fleet|47th Expedition Fleet]] towards the end of the Great Crusade, Heliosa (as it was then known) was part of an extensive planetary alliance that covered the majority of the [[system|systems]] within the '''Ark Reach Cluster'''. When the leaders of this alliance refused to join the Imperium, the Astartes of the 47th - the [[Word Bearers]] - and their attached Army units were turned loose. For reasons unknown (although presumably because of the size to cover and the relative power of the Ark Reach resistance) a significant portion of the [[Space Wolf]] [[Legion]] were tasked to the campaign shortly afterwards, with forces from the [[Thousand Sons]] subsequently assigned to aid the compliance as well.<sup>1</sup>
Ark Reach Secundus, the Imperial designation for Heliosa, was the last holdout world in the [[subsector]] and as a result suffered military assault by formations from all three Astartes legions led by their [[primarchs]] and all the resources available to them. Once their inevitable defeat was realised the kings of Heliosa attempted to surrender, but this offer was refused by [[Leman Russ]], who led his legion into a determined sack of the last Heliosan stronghold and slaughtered all the defenders.<sup>1</sup>
