but even within these you could play around quite a bit, say for example you fluff them as ghosts of the bog, you'd get to decorate the mostly empty bases with a lot of water effects and you could even apply the same dirt and tufts on their crooked backs, as if it's the swamp itself rising up to kill
or you could think about what to do with the robes first and foremost, maybe each ghost is wearing as robes the banners of some faction or the heraldic device of some nobles, maybe all the robes are the tattered pieces of an enormous map or spellbook (where you can get mad scrawling in coastlines and routes or texts and magic circles, all over an off-white paper colour), or maybe the robes are swen together flayed skins, or reflect the emptyness of the stars
