Wraith

A wraith is a spirit that can no longer maintain its form and becomes malformed. In the Continent of Gehenna, for example, there are thousands of wraiths, which were once invisible spirits, such as spirits of the water, land, wind, etc. They cannot be killed without first destroying the land itself.

Without sustenance, the spirit becomes irrational and malicious. The practice of Tocathianism came about due to the wraiths, which is a method of appeasement and establishing a relationship of mutual respect between the spirits that maintain the land and the people that dwell within it.

Lands where many wraiths dwell are referred to as plaguelands. The soil is infertile and black.

From the writings of the theologian Moxotl:"The existence of the wraiths is altogether a tragic thing that can be tied back to the Divine War. When Gehenna was ripped asunder by the clash of Azrael's armies and those who would stand against them, the spirits first became unable to sustain themselves. The land bleeds because the spirits which sustain it bleed from the wounds dealt by that War. When the Gehennan peoples fail to bleed for the spirits, they become unable to sustain their forms anymore.""The spirits cannot help themselves when faced with starvation. Once-benevolent spirits turn into vengeful and ravenous blights upon the land. The land itself become unlivable, hostile, and the wildlife becomes corrupted and inedible. Plants either refuse to grow or are irrevocably warped by the starvation of the spirits. Things which should be, become what they never should have.""As far as Gehenna has seen throughout history, it is impossible to reverse the process of a spirit's corruption into a wraith. Every wraith is another bleeding wound upon Gehenna, and above all else the prevention of their deterioration is the objective of a Gehennan's life. Without sacrifice, without the tribes, Gehenna itself would become a massive bleeding wound upon the world, spreading outward and corrupting all in its path.""That is the cause for sacrifice."""
