Opposite the Core, seven hexterranes of Coricál Ailék are occupied by the <Crimson Opalescent Arpeggio in F> Emergency Reality Enforcement Facility. A complex constructed in response to the ongoing work of OPERATION VACUUM AVALANCHE regarding physics-based threats and SKYSHOCK VOID/SKYSHOCK YELLOW scenarios, the EREF is a system engineered around 36 of the largest selective ontology evocation systems thus far constructed, configured for coordinated operation.
In concept, the EREF is designed to use the stored power of the Coricál Cirys swarm to reinforce the laws of nature as they currently stand throughout a large bubble, encompassing most of Imperial space. This is intended as a protection against major false vacuum collapses or other large-scale reconfigurations; effectively, preserving the cosmic status quo within a de facto cystal universe.
Unfortunately, it has been deemed inadvisable to test the EREF. While in theory the activation of the facility within the status universe should have no discernable effect – as determined by small-scale experiment – even the slight possibility of miscalibrations or unknown unknowns is considered too hazardous for a large-scale deployment.

Our Dragons Are Different: Inasmuch as the eldraeic mythological aman (“dragon”) was – if you believe “certain not-entirely-accepted parahistorical theories” – imagined in the image of the local Precursors, as were a number of other similar-looking mythologae of the known galaxy. What’s known about them is that they were about the right size and shape (from the ruins), scaly (from the fossils), near-solipsists (like the rijzh) who ended up wiping each other out through inability to cope with each other’s’ existence, and possessed of technology which, while in general not all that exotic compared to the current galactic mainstream, included some ontotechnological wonders or natural gifts that made them dangerous force-of-nature-level Reality Warpers to everything around them.
And they’re also responsible for the existence of various of today’s species (starting with the eldrae), various acts of ecopoesis and ecological modification, and contributing significantly to the Galaxy’s piles of archives and ancient, dangerous artifacts. (And, of course, tend to get other examples attributed to them because, well, they’re there, belike. Despite not being the only older-than-elder species out there.)
All other dragon-like characteristics are from these extrapolated.
(There are also the ékaláman, translated as “wyvern”, which look like small, non-fire-breathing Western dragons – reptilioid, following the bluelife hexapedal model with the mid-limbs turned into wings – but are not so much terrifying magical beasties as hard-to-kill dangerous flying predators and damned nuisances to people living in their home range, and specifically to their sheep, cattle, and – if flocking – children. If you’re going out, don’t forget your clockbow.)
