A hilly region a few hundred miles away from Varian's location.
Soldiers from the base who should be fatigued and resting rushed to the frontline staking their lives.
Even though they maintained a strict posture, they were far from their optimal condition.
Every soldier had a strict shift—typically around 16 hours of work a day. Anymore than that, their efficiency would plummet.
However, even working for sixteen hours, guarding the borders against a belligerent species was easier said than done.
Every day, there would be hundreds of small skirmishes. Most of them were Abyssals trying to sneak in and reach the mobile bases with explosives.
Other times, they would be specifically targetting a crucial infrastructure. If it was lost, then they would slowly gain dominance over a small area.
If they let it slide, those small areas would add up and they would loose a big chunk of their land.
