I recently implied in an RP that a dead Hero C was part of an undead horde that attacked a unit of Daimons alongside her living cousin. This happened IG: cousin showed up in the capital that she died in, next turn the Undead that were camping out there, sitting out battles and eating peasants, fought alongside him (The only attacking human unit) because they were "out for blood". It was pretty glorious, but I dunno if it falls into the same vein.
