The magical dust from the very pouch of the Dream King himself, Dream Sand as a hallucinogen that makes hallucinations real – and makes reality hallucinatory. A user of Dream Sand can mutate the flesh of anyone near enough (and it’s unclear how close that is, although line of sight seems likely), can entrap others in dreams and can prolong their own life far beyond any need for other sustenance (although not without considerable physical wasting – the magic keeps the body alive without them, but the body still needs food and drink).
Fortunately, Dream Sand is kept tightly controlled by the Dream King (whether that be Morpheus or Daniel), and it is only in rare circumstances that any human gets the chance to become addicted to it. The 72 year long imprisonment of the Dream King for the Magus Burgess was such an occasion, unfortunately, claiming the lives of at least two people and very likely more.
In many ways, Morpheus is a poor choice for Dream of the Endless. He is a creature of routine and order, and his realm is, inevitably, a nigh unto formless chaos with a few stable points – that constantly move in relation to each other.
It should come as no surprise that he has tried, on several occasions, to make his realm more orderly. One such experiment involved an alien hive mind species dwelling on the planet N’Chak’Fa, a species known as the Gaim.
An insectoid race with a ferocious rate of evolution, Morpheus attempted to shape them into something that would cushion the Dreaming. A race where some members would be permanently asleep, having carefully pre-programmed dreams, while still connected to the waking minds of their fellows via the hive mind, which would serve to stabilise the Dreaming somewhat. Morpheus hopes that his realm would still serve its proper function, but in a more orderly fashion.
And for a time, it worked. It truly did. But as the generations passed and the Gaim continued to evolve, the newer dreamers among them found the experience increasingly taxing. They would sometimes awaken, and when they did so, they would be irretrievably mad (or Erratic, to use the term preferred by the Gaim). And this happened more and more frequently over a period of several years, until the Hive Queens (who direct Gaim evolution), were forced to take notice.
In very short order, they directed Gaim evolution along a path that took them away from the need to sleep at all – while their bodies still need rest, their minds remain forever connected to the hive mind, and never asleep as humans would understand it. And Dream of the Endless, and those of his servants who still remember these events, still mourn the loss to the Dreaming of an entire race.
There’s an almost omnipotent group of pale-skinned anthropomorphic personifications who represent (and to some extent, control) various aspects of life and reality. They are best known by their collective name, which starts with the letter E.
