How and Why did Sylvanans Windrunner go from a ghost to a zombie?
so when Arthas killed her back in W3 he turned her into a banshee which is an ectoplasmic ghost and not a zombie. she’s available for the rest of that mission as a non hero unique unit. she’s not seen again until the frozen thrones undead campaign where she is a hero unite called a dark ranger where without explanation who has went from a floating ghost to having a corporal body.
she never stops being classified as a banshee but she still went from being a ghost to a zombie. (also when I say zombie I just mean any undead that has a physical body as opposed to an ectoplasmic ghost entity) she clearly has a physical body and isn’t a spectral entity anymore. in frozen throne she Talks to other Banshees that look like they always do (ghosts) and in wow we can encounter Banshees that are the same ghosts from W3 so it’s not like they retconned what Banshees are.
is their Any official in universe explanation of her change or is it the type of thing we are not supposed to think about?
