Exile

When referring to extraplanar beings or even gods, exile is a term for banishment from the Material realm.

Though creatures from other planes and especially gods and demigods are enormously powerful, when they walk upon the physical realm they submit themselves to certain physical rules. As such, it is generally accepted that any being on the physical realm can be harmed or even killed, though the task may be great indeed. Exile occurs when the extraplanar creature's physical manifestation is destroyed.

A being that is exiled cannot reenter the physical realm for what is believed to be a several centuries in Relian time, though none know for certain what keeps this universal rule maintained or whether or not it can be broken.

In order to truly kill a planar being, the deed must be done on that creature's home plane. For this reason, the practice of sealing particularly dangerous entities has arisen on Relia, though it's usage is rare and highly advanced magic.
