The basic idea is to get a SWAT patrolling Stain early game and defend it, until you have the resources to drop an Omen and Guardian in (home guard + mastermind), possibly with a Hired or two (or recycling that with dmg control/proofread) The Bastion + SWAT patrol combo is pretty powerful for keeping regions, it means you get a ship that is invulnerable to conventional attacks, and the other locations also help keeping your ships from being murdered.
