[@Blizz] Huh. Oddly enough, half of the listed ideas have canonical lore equivalents in this world.
[list]
[*]The Mercurial Shifters, a.k.a. "voidspawn," are shadowy, shapeshifting monsters from a hellish parallel universe. They are the sworn enemies of humanity, except for a tiny handful that have thought about it for themselves and decided otherwise. They were once more technologically advanced than modern humanity until the Ancients (and then Regret) pummeled them back to the stone age.
[*]The Wraithkin, so named for being "possessed" by "ghosts in the machine," are sleek, deadly constructs given "life" and built for war against the Voidspawn. Most were destroyed in the conflict.
[*]Ghosts are very plausible. If one steps into the spiritual plane before their physical body is destroyed, they will be stuck there until a higher spirit comes to claim them. Partial ascension after death from powerful lingering regrets (like how Regret herself ascended) is a common way this can happen. Their anchor would be a suit of armor. Normally it wouldn't be mobile, but we can bend the rules a little.
