Hasis, Taasme, and The Xikru were the Firstborn of dread Engidir, and each was brought forth in an asylum or similar sanctum for the insane, as to touch any denizen of the Beyond even in dreams was to succumb to disordered thoughts and madness. The Triplets, as they came to be known, thus had none of the relatively pampered and stable upbringing that their “cousin” Qudma enjoyed.
Hasis was the first and most terrible of the three, and the one that cast the longest shadow. Known as a “he,” in a deliberate contrast to Qudma, Hasis was taken from his mother at birth for study, as it was realized that such a child meant that another from the Beyond had begun to become aware of, and interfere with, the world of matter. That she, along with every being made of matter within a wide radius, was mortally wounded by the arrival certainly did not help matters, nor did the fact that Hasis was unable to be perceived by ordered minds of matter from his very beginning.
Eventually, clad in a garment that he termed a “caul,” Hasis was taken in and raised by cultists of Sukhallu, one of many such sects that had arisen. On attaining his majority, and apparently at his “father’s” behest, Hasis began a series of brutal experiments on his followers, apparently with the intent of testing the boundaries between the world of matter, human dreams, and the Beyond. Cultists–now following dread Engidir rather than Grandfather Sukhallu–were the first willing subjects, and many were mutilated and killed for their loyalty and faith. Apparently as a method of further study, Hasis sired a number of his own children–sources differ as to how many, but certainly at least three and perhaps as many as twenty–and set them up as majordomos in his growing cult. The relatively large number of Engidirans extant today can trace their lineage to these.
Eventually, it seems that Engidir grew tired of the experiments, finding them fruitless or perhaps simply dull, and took personal control of its son to put an end to it all. It was then that the cult–or such that Hasis had easily at hand–was slain to a one in the Red Omen. Particulars are difficult to verify, but it seems that Hasis slaughtered his followers and his own children one by one, systematically, before using their mangled bodies and their spilled blood as elements in a massive eldritch sigil. He himself, brought down by some secret method whispered by his “father,” seems to have sealed the ritual.
The area is today known as the Rift, and remains dangerous and off-limits. It is said that anyone with the blood of Engidir or Hasis is eventually, inevitably, drawn to that place where the veil between the world of matter and the Beyond is at its thinnest.
