Druzayast

Eldritch Horrors only in the sense that they're simply not natural, the Druzayast, Firstborn of Crux, were the original inhabitants and owners of Crux. They're big.

History
Due to literally living before the gods got to making anything, so much so that they didn't even know Crux existed at the time, the Druzayast have literally almost no history. They just were. They sprung up from matter on Crux, and before Shuliak gave Crux magic, wielded sorcerous powers; proving just how unnatural they were even for what they were. They were so powerful, in fact, that it was the Druzayast that brought the gods to Crux; their magic was so powerful that it was investigated by a god interested in what could cause such effects, leading to the discovery of Crux.

With the arrival of the far more powerful gods, the Druzayast were driven from their homeworld and into another domain from which they could not escape, so that Crux could be converted into a nexus for which the inhabitants of the Spheres Beyond could use to cross the Spheres at a much faster rate than normal.

The Year of Wrath completely shattered that plan, as one of the Druzayast, Qun Qunuq, was unleashed back onto Crux. Merovech stabbed it though, and now Qun Qunuq is mostly dead.
