Event Weapon Imitation

A so-called Artificial Causality Phenomenon Weapon (模倣事象兵器, Mohō Jishō Heiki), or Artificial Causality Weapon, is a non-magical imitation of the Nox Nyctores created through advanced technology. These devices rely on atomic power rather than seithr to function. The Idea Engine is an improved version of these devices. These weapons create a resonance effect in proximity to a true Nox Nyctores, as the Nox "recognises it as something similar to itself".

Iron Tager is known to possess (or be) one of these weapons.
