Alter (Creature)

An Alter is a human that has died and been ressurected by the Necromancer. Currently, there is only one Alter - Vesper Vagus. According to the Master Guard, the imperfections of the Necromancer's ressurection are: The Master Guard also says that they are "no longer human".
 * They can no longer grow up. (whatever that's supposed to mean)
 * They barely feel pain
 * Their body is "overall malfunctioning"

It is suspected, but not confirmed, that there is a briefly-shown character in Episode 1 that is also an Alter.
