On the planet of Soluin, the Phaleks are enslaving rebels and others to work in their Phalekanium mines, As i'm sure you can imagine, the Rebels weren't too happy about this, and raised a large army of Rebels, dark ages and Machine uprisings.
The large horde would attack a small empire remnant outpost which was being visited by PEE alliance members.
If the Delegates died, they might leave the planet in peace and let the current factions kill each other...
Here is the first wave
and that is what the outpost looked
I didn't take any pic of the actual battle, but here is the end for you
(Trundle of ultimate badassery)
In the end I decided that the only remaining imperial(A Phalek) had a button in his travel machine that teleports in help.
Lots of heroic sacrificing and stuff.
And so the planet will be pestered by Phaleks for a long time to come...
