Ehh, I wouldn't consider GhostBlade to be a historical fiction, since it does not take place in a real location. It does have amazing art, though!
IMO "historical fantasy" uses a setting that is, or was, a real place from a specific time period of the past, except with fantasy elements added. Like, the setting in my own comic is heavily based on semi-ancient Korea, but it's not historical fantasy to me because it's clearly not Korea -- just a place that happens to look a lot like it.
I don't think I'm subbed to any historical fantasy comics here that's still updating. Though Heroes of Thanatopolis has some historical elements going on in its current arc -- it's an afterlife setting, and right now we're dealing with the ghosts of some historical figures?
