I feel like we need to try and push right across the subsector to try and stem the choas "Infection" From spreading out across the sub sector. We can integrate/conquer the rest of the systems at our own pace, but leaving chaos to run around near unopposed is not only a good recipe for horrid things, That gives chaos access to more weapons, More slaves, More sacrifices that can turn straight into either more Forces or more bullshit sorcery.
Chaos may not look like it, but depending on the "faction" They can operate similarly to a Hive fleet in strategic movement, Hoovering up undefended planets to addto their own mass/Power etc or literally summoning warbands to reinforce them.
Worst case scenario they try to set up a Port/Forge, which basically acts as a beacon to Chaos warbands to come and get repairs/Slaves/trade/ all the horrid things that happens at the equivalent to Chaos tortuga , which means they could pull forces from outside their warlords personal strength/ability to subjugate to help them.
At minimum, we need totry and reestablish a defensive line on valhidem... and what the fuck happened to Sagget? God dammit I hate chaos's ability to just pop up from nowhere.
We probably didn't help taxing their fleets and stressing them out like we did, But We were like 10% at fault at MOST.
