Yes we have concept about it but its in progress. We try write book now for future release and in Fiery Dawn album we have small part of it in booklet, like teaser. It was not really plan, but last 3 releases very connected about concept.
So here about this 3 red guys:
A flat platform sways in the void. Three gigantic creatures hover above her in robes crimson like blood. The heads of the unknown are hidden by hoods, like those of priests or monks. Outwardly, the giants look like earthlings, only their skin shimmers with the same light as the crystal. Adepts hold energy spheres in their hands. The flashes surrounding the platform form an ideal circle, woven as if from a myriad of multi-colored sparks. And high above the heads of the creatures hangs a golden structure of stunning beauty, with a spire extending upwards.
Suddenly, the astronaut realizes: it is the source of the ringing melody, thanks to which he was here. But the insights do not end, in an unknown way he seemed to be connected to the source of information. Now the man knows for sure: the adepts hold the worlds in their hands. The mind freezes and completely obeys the flow of data.
The being in the center is clearly the most powerful of them all. The power of his intellect, wisdom, and endless knowledge cannot be described in words. Like a Cosmic Deity, it preserves and guides entire worlds, and perhaps galaxies and universes. Adepts on the sides look no less impressive. Yet the astronaut feels that they are different. The personality of each is unique and incomprehensible, but the mission, apparently, is common - to protect the worlds entrusted to them. And now something more is happening than contact with the ancient mind, about which earthlings dreamed so much. By absolute coincidence, a lone astronaut collided with something unimaginably ancient and powerful - the foundation of the entire universe, the center of the forces of the universe.
