Withergeists

Withergeists are entities of chaotic darkness. Originally of the Void, they are enraged by the Light of existence. Their presence in reality is based in one goal; the destruction of everything. They make their way through the cracks in reality, taking form as incorporeal spirits that decay all that they touch.

But existence in reality is painful for them, especially the light that fills it. In addition, most are no more intelligent than animals in their goals of destruction. This combined makes the weakest of their number no more dangerous than a plague of cockroaches or mice. Even most of the more powerful withergeists lack the cunning of man, making them simple to deal with once one has become familiar with them.

The real danger, then, is not the withergeists themselves, but those who seek to use them. By bonding with a withergeist, mortals can gain a number of powerful abilities- including the ability to control other withergeists. Some take this power for their own gain; others believe that they can use it for good. All, however, eventually find their perspectives warped to align with the spirits that grant them their power.
Inevitably, this power will destroy them, and their spirits will join the ranks of the withergeists.

The Fallen

The greatest and most powerful of the withergeists are the luxsprites who were corrupted by the Witherlord. When other withergeists see only a tower to be torn down, the Fallen see a stronghold for an army that will tear down a kingdom.

A few of their number are:

Erechon, former King of the Luxsprites, is adept at manipulating life- and death.
Verdellia, former Queen of the Luxsprites, specializes in extending her ability beyond her original host.
Adrastos, former Prince of the Luxsprites, has mastered creating dark reflections of existing energy systems.
Naseir, once a great scholar, gives his hosts the knowledge to forge implements of shadow.

The Fallen work to bring about the return of their master, a spirit more powerful than even they, known as the Witherlord.

The Witherlord

The moniker of "Witherlord" can refer to two things. First is the mantle of dark power that represents Chaotic Darkness itself. This mantle enjoys limited sentience but lacks consciousness, rendering it essentially impotent until it finds a host. These hosts also bear the name of "Witherlord", for they merge with the memories and knowledge that the Dark Mantle holds.

It was the first bearer of the Dark Mantle that destroyed the luxsprites. It would not have stopped there, had it not been for the intervention of the Ennullers. They destroyed its host and trapped it in a prison inside of a prison, sealing it beyond the reach of any who might be tempted by the power it promised.

Or so they thought.
