Very cool idea for a mod!

what factions are you planning for?

I'm looking to potentially replace the text for the 4 existing factions.
Next one could be:
- chs (may have to split this one to an other mod)
- tmb
- cst

Ah, okay, well here is my hat in the ring for a few of these. Feel free to edit.

=================================================
Vampire counts

title: "Mountains of corpses!"

"Life for mortals is already hard, but they can be surprisingly tough, however when presented with a lack of food and disease they tend to die like mayflies. Which in turn creates a surplus of corpses that can be monopolised by any necromancer who happens to pass by, adding the fresh corpses to a rapidly growing undead legion."

=================================================
Orcs:

title: "tribes merge!"

"A wandering tribe of greenskins has run into one of the more settled tribes, after several days of fighting each other, the nomadic warboss has been slain with his remaining boyz being absorbed into the victorious tribe, doubling their numbers!"
=================================================
Tomb kings

Title: "Bones in the sand"

"Previously hidden under the sand but uncovered by a sand storm, an army from one of the long lost tomb kings has been discovered, but their lord is missing? Even so, his rivals have taken advantage of his absence to add some new recruits to their own armies"
=================================================
If you are going to do it for the Vampire coast too, I might have an idea...

Title: "Ships lost at sea"

"Ships crossing the great ocean have started going missing, either getting lost, destroyed by turbulent seas or getting attacked by more and more bloodsucking freebooters. More bodies going down to Stromfels depths means more bodies for the undead fleets to add to their crews..."

really nice!

Okay here is one for Norsca

title: "Norse Moot"

"Assuming that Norse tribes don't kill each other on sight, an uneasy pact will form and a 'moot' begins. Moots can be two or even several tribes, gathered by chance or decree. A large fire pit is usually dug and the tribes set up camp on opposite sides. A monstrous beast will be hunted and set to roast on the open flames before the talking begins. Usually, this consists of boasts followed by lethal tests of strength and skill, with binding blood pacts made at the end."
