Well, I remember someone (might have been DaBank) arguing against a demon warband, based on the fact that the demons 'couldn't be afraid of what goes bump in the night, cause they WERE what went bump in the night.' Likewise, I like the idea of the Dryads being a NON-warband force, cause as much as the dryads and tree spirits MOSTLY trust the elves, they'll never COMPLETELY trust the elves. It would make sense if the wood elves would OCCASSIONALY be attacked by woodland forces, amongst the confusion and desperation of certain woodland forces. A dryad warband being attacked by the forest doesn't hold up as strongly.
Scenarios: cool. I'll finish 'harvesting' campaigns and mordheimer for good, existing scenarios, to save us trouble.
EDIT:
Rewards: I think the following rewards seem to fit with the theme, plus who can take them.
REWARDS OF THE LADY - The patron goddess of Bretonnia, in her purity and infinite beauty.
TAKEN BY: Bretonnians (old), Bretonnian Chapel Guard, Bowmen of Bergerac
REWARDS OF ARIEL - The spirit of life and rebirth, leading the soul searcher to see their important role in the natural order.
TAKEN BY: Wood Elves, Horned Hunters (, Bowmen?)
REWARDS OF THE GREAT HUNTER - Whether it is Taal, Orion, or perhaps something far older and savage, the spirit walker seeks the inner strength from the greatest hunter ever. The young warrior becomes a hair's breath between ultimate serenity and savage rage, and learns how the hunter and the hunted are spiritually bound. Respect for your quarry, even as you kill him with primal force.
TAKEN BY: Wood Elves, Slayers, Horned Hunters, Savage Orcs, Forest Goblins, Beastmen
REWARDS OF THE DEVOURER - The darkness that grows deep in the forest, in the form of rot, mushrooms, and creatures older than the trees. The chaos gods are here, unseen, whispering promises so faint that it sounds as innocent as the rustling of the leaves. (Same as Rewards of the Shadowlord)
TAKEN BY: Beastmen. (Also Marauders, Norse, and Possessed, if they happen to be in the campaign.)
Of course, Mercenaries HAVE no Rewards chart. They find their gods in books and cathedrals, closing themselves ever inward. Only the forest dwellers know that the path of enlightenment and spiritual fortitude is drawn from without, among the brooks, trees, and rocks of the surrounding area.
I like reusing the 'Shadowlord' table with another name. Saves us work.
