General Info: Warp-Aci are not native to the plane of Furrae, and in some ways do not strictly exist there either. Their native plane is devoid of light or feeling, and they curious creatures, eager to experience the corporeal world.
Summoned by a caster, they are given a body composed entirely of dark magic, which is bound to the
summoner and controlled through a marking on their forehead (this can be set by the caster - for a 'Cubi it is typically their clan mark). When the summoner dies, or if the Warp-Aci is released from service, the spell will expire and the Warp-Aci will return to its native dimension.
Warp-Aci are typically used as familiars, and messengers. They are particularly valued for their
ability to slice through the dimensional boundaries with their tails, allowing them to teleport
people and things.
Since they are somewhat high-maintenance and finicky, not many races will bother to summon them. However, they are a favourite of 'Cubi and teenage girls.
