This is a Lore Arc, there will be many more events related to the chapter that's currently going on (Chapter 1)
Chapter 1: The Anomalous Fleets
Rules:
Unlike most entities in most events, these ships are destructible, and are one of the ways to complete this chapter.
Keep in mind that rewards for (military) and (diplomatic) conclusions are different from each other.
In a case where combat ends with the entirety of the participating faction's present forces were destroyed, the fleet will immediately leave and the faction would have "Failed to survive the encounter."
You can only call in so many reinforcements. Keep it to at most two waves.
Do not use Lore powers that would outright destroy the fleet without a proper fight - another will just take its place. If this continues, the event in that sector of space will be non-canon and the faction will automatically fail the chapter.
Other faction help regarding this event is limited to just alliance members. Enemies could also join in, but only for combat purposes (whether it is starting, continuing or stopping a fight does not matter)
The Behavior between Anomalous Fleets WILL change, do not be surprised if you get a way different beginning than other factions.

Update 2:
As of this update, the following factions have completed this chapter:
XA Empire (Diplomatic)
The F.I.G. are still in combat, for some reason the Zankarans decided to help out despite their differences.
The Mikrelian Defense Force sent in a large fleet led by Rear Admiral Lewis to destroy the Subcore. They moved on to Phase 2.
The Crimson Alliance... Well... Are still talking.
The Blood Cult One-Shotted the Subcore (An exception to the "fair fight" rule because I pretty much expected that) and found some Debris, but the Crimson Alliance stole it. DRAMA!
The Junkers are really annoyed at the Subcore's language barrier. Phase 1.
The I.R.V. Haven't done anything because I neglected them. Whoops.
New Anomalous Fleets have been detected in the following Faction Territories:
The United Earthen Empire
The Varangian Guard
