Captions are below pics. Apologies in advance if the pics are too large (if it's really bad, post something and if enough people complain I will most likely take the time to re-size them).
So without further ado, here is the small amount of backstory I developed and the three main factions.
In late G.R. 2010, the Rann'd'umm Galactic Forces (RGF) have begun expanding their territories. This will be a slow process, but it's time we made ourselves known. These are our main policies:
1. Peaches are not tolerated. All citizens and soldiers of the RGF must shoot them on sight. The only exceptions are for government-authorized interrogations.
2. Drugs are not allowed, except for authorized medical prescriptions. However, alcohol is, and you may drink it whenever you like. The only exception is Maniac Beer, which must be delivered to a government official immediately. If you are found drinking Maniac Beer without authorization, you will be executed without trial.
3. The RGF sides with the Immortals. Any proven treachery will also lead to execution without trial.
And now, the battle backstory.

The RGF have intercepted a drug transferal between peaches and yellows. Seeing as how this violates two of our three major policies, we have decided not to immediately execute the peaches. Obviously, this is a large operation, and we need information about it.
On the left are the drugs, and on the right are the prisoners' weapons.
We are currently holding the peaches in a small outpost 3 miles south of our capital city, Kiela. The outpost is codenamed ARK.

As you can see, the commanding officer (Lancer Robin) is waiting for authorization to interrogate these peaches. Also, a trooper is taking a break and enjoying a beer.
Robin is the RGF's hero.
(Note: Holy crap, my dog sheds like crazy. Dog fur will most likely appear in several places)

These two are guarding the peaches (and seemingly having a small argument).

Here are the three peach prisoners, awaiting death or torture.
(Note: Now this was a hard picture to take. I ended up having to put two legs of the tripod on the elevated baseplate, while not smashing anything. AND, there's more dog fur. Dangit!)

The outpost is fairly well protected. Shown here is a Xavi-2P AI turret.
(Note: See the next pic for what that blurry thing in the bottom right is.)

Here are the ruins of a town square, and Pierre the sniper. On the left is an ancient statue, which is not going to come alive and be a secret faction. It's just a statue.

A better look at Pierre. He was in my HH submission, Assault of Namelessia (link)

And this is the right half of the battlefield. Note the hollow blue thing (hint hint) and that storage container (hint hint).

The full battlefield. Note the red-marked auto-turret, that's controlled by the RGF and can be aimed at any target within range. Also note the blue-marked chemical pipe (hint hint).

*Insert swoosh effect here*

Looks like somebody has Farce powers...

Ouch.

THUNK

"Sending in escape route."

"Please take stairs carefully."

They dash up the stairs as quickly as possible, heading for their weapons.
The Snake Plisskin look-alike (hereby referred to as Slake Diskin), despite being stunned and disrupted, still manages to warn the rest of the base.
The alarm is sounded!

The peaches get their weapons as the RGF base get theirs. It's a classic Mexican standoff!

"There's no way we can win this. Teleport us out of here."
"Right away."

They 'port away...

and appear over here.
"Sorry, but they've got a dampening field. You can teleport or go in, but not out. Sending reinforcements. As long as you're there, try to recover the drugs."
"*sighs* Fine. Send them in."
(Note: This is my lame excuse for why the peaches don't just leave. They have to get the codes from Robin's communicator to get out of here)

A cycle with two troopers drives in.

Dark Vayderr jumps in.

As does Jetpacky. That thing he's holding is a beamsaber tonfa, medium CC weapon.

The entire group.
Dark Vayderr is the Peaches' hero.

Suddenly, a Temporal Flux portal appears!

Out march a group of Haunted Heads.
(Note: It took me forever to pose them like that, so they wouldn't just fall on that slope. I hope you guys appreciate it.)

They eerily raise their arms and march towards the RGF.
The peaches are moderately unnerved, and tighten their grip on their weapons.

Their Necromantic Leader appears through the portal as well. He is radiating shadow magiks so powerful they are visible. (-2 on all CC skill rolls against him)
He's obviously the hero.

He quickly talks with the peaches, saying that they are after the yellows (and something about how peach flesh doesn't taste as good).
Dark Vayderr is slightly insulted, but agrees to the truce.
