Lanterne de Fantasmagorie

A curious lantern containing a wandering spirit.[spoiler] the lantern itself accompanied Nachiroux when she arrived in Alstella as an infant[/spoiler]

When it partners with an individual who serves as its medium, it has the capability of observing their experiences, as well as venture off on its own into the labyrinth, commanding the puppet soldiers to do its own bidding. In addition, although Eureka is its main medium, it tends to dwell itself onto beings with a defenseless, weak spirit, or a low sense of awareness.

The Lanterne cannot interact with the world directly, but is capable of limited communication with its mediums and a select few astute individuals who can see it.

As for the wandering spirits themselves, many speculate on who or what they may be. Some believe they are many, while some believe they are one. Some believe they are arbitrators, and some believe they are merely observers. Whatever they may be, one thing is for certain- they are omnipotent beings choosing to involve themselves in this enigmatic tale.
