The Arma Caeli are a race of mostly warriors living high up in the sky. They are the original inhabitants of the reflection. The Arma Caeli have since eons prided themselves on conquering newer realms and are feared as a result. Their name more acurately describes the special armor they wear and honor, so much so that they use it to refer to their species itself. These beings primarily rely on a power called Vis that they are all born with - it is magic in its purest form. Vis is akin to an electric current running through their bodies, one they can shape and bend to their will as they get older. Vis is also the force that allows them to wear their armor directly on their skin, to fly, and to command their weapons. It seems to protect them naturally while inside the reflection. It is highly rare to ever meet a warrior Arma Caeli without their precious armor, and if it happens, it is a sign of great trust.
