|The nightmares are most highly feared among all creatures which stalk the Dreamworld, and rightly so: for they are utterly unnatural. They do not fill an ecological niche, do not procreate and spread life, do not have any ancestry or native origin: they simply do not belong. Intruding from abstruse planes of existence, they impose their aberrant corporeal forms to one end: Destruction.|
|Specifically, the destruction of the dreamkeepers. Thirsting from beyond time to undo the tapestry of creation, they level their nihilistic vendetta against sentience wherever it may be found - and desire exceptionally to wipe humanity from existence.|
As long as their dreamkeeper lives... A condition which the nightmares are only too eager to alter. Capable of unlocking human vulnerability with the premature murder of a dreamkeeper, their ultimate ends are far more ambitious in scope. Absolute eradication of every last dreamkeeper would leave all of humanity exposed, victim to the whims of the nightmares' nonexistant mercy.
Successfully seeding their presence in the Dreamworld aeons ago, they continually manifest there to fulfill this purpose.
They can enter the Dreamworld at only one location - the fabled desolation of Bralgu, where they incubate within the twisted nest of evil, Malangi.
Some nightmares may opt to express their power in maximum physical form, attaining colossal size and strength. Others may choose to mitigate their physical might, and focus the remaining potency of their being into residual supernatural abilities.
An additional limitation on nightmare manifestations is their cumulative threshold. The more nightmare power exists in the Dreamworld, the more difficult it is for further nightmares to manifest. When their collective presence peaks, it is impossible for more nightmares to gestate. It is the innate metaphysical balance of the Dreamworld that causes this phenomenon. Were it not for this naturally limiting threshold, innumerable nightmares would smother reality.
In addition to metaphysical constraints, manifested nightmares are burdened by the task of maintaining a living body. They must feed and care for themselves like any other creature, or face death.
|Physical expiration is less significant to a nightmare than it is to other beings, however. Although frustrating and insulting, death for a nightmare is only temporary. Their malignant spirit can instantaneously return to Malangi, and again join the queue for manifestation. Despite their relentless nature, the nightmares suffered a cataclysmic defeat centuries ago. Diminished and endangered, they concealed their existence for generations, their bitterness simmering in confinement as they slowly, incrementally regenerated their strength. Awaiting in the patience afforded by pure malice, the time of their reprisal is drawing near - unsuspected by the dreamkeepers.|
