Ashes.
Generally, it refers to the remnants after a corpse is burned by flames.
However, in the magical world of the Boundary Land, ashes are not something commonly seen. Once they appear, it often means that they have a special purpose, usually used to create combat puppets from souls that have not returned to the Returning Tree.
As somewhat cruel spell creations, their Effect is that the soul of Life will be imprisoned, residing in a catalyst made from ashes of its corporeal existence. When needed, the soul can be summoned back by the user, reappearing in this world without release.
Of course.
It is generally used for combat purposes...
—To be fair, this is indeed a very strong technique for creating summoning Spirit Puppets. Almost all the Power and fighting ability that the Spirit Body had in life can be temporarily reproduced by the ashes...
