You know... why not zebras? In fantasy setting, I suppose horses don't need to be the same color. Or horses.
I am starting to lean towards a medium-low fantasy concept, or at least something less than the Warhammer world. I've actually been thinking about a setting quite a bit and finally did decide to completely part ways with Warhammer. I think the major fantasy elements will be:
Non-human but "humanoid" races. At this point, in the part of the world in which my campaign will be set, it will be mostly humans, with ogres, and small numbers of giants, great orcs, and swamp goblins. There used to be elves, but as far as anyone knows, they're all dead. Rumors of other races in far flung places. Some may be introduced as part of the narrative.
Undead. Obviously. But this is a new & foreign thing, as far as my Marienburgers are concerned.
Magic. Mostly rare and powerful, and manifesting itself through items and creatures rather than mages flinging fireballs at each other on a battlefield.
Fantastic beasts. See previous item.
The divine. Divine intervention will be about as common as in the real world.
Technology will be mixed. I'm still attached to the Empire & renaissance, so gunpowder, pikes, etc. will be around, but I will probably be leaving out any steam tanks or robo-horses. Navigation & ship-building will be slightly less advanced.
I've quickly sketched out a first, (very rough) draft of a map-like thing. The highlighted area is where the action will happen, centering on the city of Marienburg and the surrounding hinterland.
