Imperium Forces dive deep into the darkness hoping to bring the light of the Emperor to sectors lost to Chaos. The first wave of Astra Militarum accompanied by Battle Sisters and a Knight have made contact with the enemy and it is Abaddon and the Black Legion. Dark Expansion is a mini-series involving Imperium Forces challenging Chaos' reign on Imperium Nihilus. Brought to you with support from the many people who took part in our Dark Expansion fundraiser. As part of the campaign supporters had a chance to name a warrior in these battles. In these inter-connected games named warriors, if they survive, will make it to the final battle but those that perish are gone forever. The rise and fall of heroes!
