Sombreroman
A familiar ship warps in

The ship immediately sends frantic broadcasts, while heading towards the opposite side of the sun.
//Transmission Start//
WHAT THE HELL, WHO THE HELL IS AT THE COMMAND OF THESE FLEETS. DID YOU NOT THINK TO LOOK FOR THE OTHER FARAGAUT??? THINK ABOUT IT
//Transmission End//
It is now brought to your attention, that the other faragaut has managed to slip past the fleets engaging the Tau-ships, and is almost at the Dyson sphere, having approached from the other side of the sun, to not be spotted by ships being launched from the sphere.
A transmission from the other faragaut is received:
//Transmission Start//
Hahaha, this ship is not a rebel one, but I'm under orders to destroy the dyson from the now dead Graham. He probably wanted to do it to spite you Tau alien scum, Long live the ISC.
//Transmission End//
A transmission is heard from the Un boarded Equality class:
//Transmission start//
Seeker? Oh thank god, please help us out when you deal with the Faragaut, I want to go home.
Pass me the mic, now! stupid cat
oh yes ma'am
Right, seeker this thing is not going to hold out much longer, we need to get out of here now, I hope you don't mind, id be happy to teach these humans a lesson, but my stupid crew don't want to stay, I mean, its only a couple of million worth of damage.
warp drives charging captain
//Transmission End//
A second transmission is heard from the Seeker:
//Transmission Start//
sigh, anyway today has been a huge F-up if I'm honest, For now I'm on your side, not the ISC, not The TSC.
I just wish I never found this place.
He thinks to himself for a moment, then comments:
ill assist in destroying the ISC Faragaut by the sphere. Then try and work out what the hell is going on.
//Transmission End//
Sitrep:
Now, another threat is on the horizon, and more importantly, who can really be trusted in this battle
(I thought now was a good time to actually include why this civil war is even happening here, instead of just in Tau space.)
Meanwhile, the boarding action continues as normal
The TSC ships continue firing at the ISC ships, continuing to not fire too much at the other ships. although of course, the boarding action will likely "soon" conclude their existence.
The clear confusion on now unjammed ISC comms channel suggests they where not aware of the Faragaut's plan.
Meanwhile back in Tau-Species-coalition space, the change in power has gone somewhat smoothly due to the lack of humans on most planets, however this was not how they wanted this to go down at all...
Edit: changed a lot here, I presume you have not seen it yet, so it should be fine, but its mainly the ISC related stuff.
