Thanks for the wild speculation guys,.

I can however confirm that the last installment of my "vikings vs" will be "church folk and sheep".
The idea is the same basic thing:
You roll to see where your raid has arrived:
1-2: Owl Bear Island
3-4: Ninja Land
5-6: Defenceless parish w/ sheep
Each island will have a set of terrain features so I can swap a few things and change the location completely.
The location will also decide the scenario.
The factions will be like this:
Owlbears: Some 5-6 figures. A single druid and otherwise owlbears. Terrain will be some stone henge thingy with a huge nest w/ eggs.
Ninja: Same amount of figures as vikings. 10ish. With a single "master". Terrain will be a single oriental style gate or something with some statues of the laughing buddha I think..
Parish: Some 15ish figures, possibly multisheep bases. A dog, a priest and a monk and the tough Shepherd (nearly viking). Terrain will feature a simple church and some enclosures.
In all three games the "defender" eg. the non-viking player will get a set of mushroom counters to place on the table. They must be a distance of so and so apart and so on... there'll be 3 good ones and 3 bad ones (only the defender will know). If a viking comes within 3'' of either he must eat it immediatly.
We'll - I better get some painting done!
