Across red humanity's borders, a hurricane crashed against all of the fortified positions at once.
The Red Tide Offensive had begun.
The native aliens spent so much time on building up their assault fleets and equipping them with more modern tech for the singular purpose of overwhelming the barriers that stood in the way of human extinction.
Pretty much every alien soldier yearned to do their part into driving the hateful humans back to the edge of the dwarf galaxy before wiping them out entirely!
This was pretty remarkable. The forces that had answered the call of the Red Cabal were composed of a lot of different races, cultures and other subgroups.
The full answer why this was the case would take too long to explain, but the essence of it was that the native aliens built up far too many grievances towards the humans over the past decade.
