Spectres are the private military corps of the Mages Guild in Lunaria. They are human-like constructs (Homunculus), superior to humans in both strength and agility, and highly resistant to arcane magic. While they possess keen intelligence (only used to perform a given order), they lack any form of free will.

Spectres come in many variations, and are often specialized into a certain function. They are known to be responsible for the defeat of Dalaria’s last crusade against Lunaria.
