I have read the one about new bretonia.
And that got me thinking.
On a bit of fluff from the Flesh eaters, one of the ghouls sees himself with a tabard, and his Lord with a gold shining armour on his mighty steed.
Ofc this is conjecture but it could point for the direction of the faction.
And since the New Warrior priest has a robe, maybe the faction will be a mix of Empire wih bretonia like a crusader army to re conquer the mortal realms.
