Editing Oestalan Sector (section)

===The Dance-Lights===
A cluster of eight hot, young stars ranging in size from one to two Solar masses move through the cosmos as a bound cluster. Millions of years from now, random perturbations will separate the cluster, but for now, they orbit together.

An empire of minor xenos has established itself within the cluster, for its blistering light and radiation helped to push back the Great Storm. Massive beasts forged of diaphanous currents of energy tracing itself through colossal spheroid bodies, they feed off the energy of the stars and ride currents of magnetism from star to star at tremendous speeds.

They are shockingly peaceful, for they need nothing of planets and know nothing of war, content to live in their own unique habitat, contemplating the cosmos.

Rogue Traders have made peaceful contact with them, and the nameless species, for they are of one communal mind in many bodies, has shared much information about the Oestalan Sector. These luminous beings cannot see small things like people, but they are sensitive to magnetic fields of spaceships, planets, and especially stars, and can read the motions of most of the sector's large bodies.

The Imperium has benefited from their presence, and having no particular reason to kill them, has let them be, pursuing more immediate threats. Conversation continues with the orb-creatures, and though their perspective is very non-human, they have assisted certain Mechanicus Explorators in developing a few innovative plasma containment technologies, which have been dutifully sent back to Mars under the guise of being holy relics recovered from ruins. 

Only one unfortunate accident has marred the peace, when a single overenthusiastic Magos tried to siphon one of the orb-creature's energy and bottle it for study. His destroyer-class vessel was later found drifting in the void, twisted neatly in half.The Magos, who survived the death of his ship, has reaped great rewards, left behind at his personal request by Rogue Trader Pavel. Though he has re-established peaceful accord with the xenos, he is paranoid that his secret may be found out. He considers himself the equal of Arkhan Land, and is building great renown for himself, but though his inventions may benefit the Imperium greatly, to the dogmatic Mechanicus, they are Heretek through and through. So long as none discover the lie, all will be well.
