TL;DR: We will probably get a new stratagem if we hold X-45.
The planet X-45 in the Ymir Sector is home to a lost Advanced Weapons Lab from the First Galactic War, buried underneath rubble and abandoned due to dangerously high radiation levels across the planet. The Lab was working on development of a powerful interplanetary battle station. Now, with radiation levels abated to completely safe levels, excavation and recovery of the Lab's work can begin, which would allow the eventual construction of this battle station. However, the Automatons have become aware of X-45's importance, possibly through malicious and deceitful cyber attacks. They have launched an opportunistic assault to rout our cut-off forces in the Ymir Sector.
On High Command's orders, SEAF Forces have begun amassing on Aesir Pass. Soon, we will be ready to initiate a push to break through the Automaton line and relieve our cut off forces.
Until then, the Automaton assault may be slowed, but will be extremely difficult to stop altogether. It is imperative that X-45 be held until the plans for the battle station are recovered. If they fall into the Automatons' actuators, the results could be disastrous.
The reward is the friendships we make along the way.
