I am glad to hear Citadel Collector is so on the ball with this. And yeah, a few ancient artefact 'bang sticks' aren't out of order re: Warhammer fluffiness.
And I am very glad to hear lenihan's comments - I needed to know how others felt about the idea. I am in complete agreement on being careful with the feel and theme. Warhammery stuff coming out of the fluff fits the theme well, as does some wider ranging craziness as the rift goes haywire near the end.
We're getting close to finalising stuff. I am in the middle of running a WFB campaign right now, but will find time soon to come up with a solid final draft scenario outline re: scenery, temples, traps and dangers, arriving, nicking stuff (from temples and each other), leaving, etc.
I am gonna try and put in as much of my pygmy army in as possible as defenders of the valley, like my regiment of gorilla warriors and such like. Just need to find out what they 'count as' (probably Lizardmen, possible with str 4?)
