Fulcrum Hive, was a space station made long ago, practically a relic of an ancient era by machina standards. Specifically, it was designed before the Machina developed anti-gravity technology, and so needed to actually be in space to perform zero-g manufacturing. Where said manufacturing took place was called Fulcrum Factory, a stationary hub at the center of the station. Around it rotated an inward facing ring where the workers lived off shift. The fact that the workers long ago had been human and needed gravity also helped tell one how long ago this facility had been created.

Once upon a time this had been a fiercely contested spot, and the outward sections of the the ring still bore scorch marks. It was bristling with hastily tacked on guns, turrets and missile blisters peppering the outside of the station, half of which had been blasted to scrap. Around it was the floating debris field of battles long past, space ship hulks, the freeze dried corpses of both monster, angel, and human, forming a macabre field around it. Pirates sometimes hid amongst this debris to hijack shipments to or from Fulcrum Hive, as some backwater station was far easier to burgle than anything Eos might take interest in.

There was a population of humans still aboard Fulcrum Hive, as the factory, and docking facilities were still mostly unautomated. There just hadn't been much call to upgrade the facility. They'd lose some of the only business they had left, that of rogue outfits stopping by for resupply, far from Eos and the Machina's watchful eye. It's "Zenorian XI" metal, once revolutionary for it's superior strength to traditional materials of the time, had been exceeded by the relentless march of the Machina's magi-tech. But these humans had been born upon Fulcrum Hive, and so would their children. The jungle world below, Zenor, though lush and verdant, was exceptionally dangerous. It was dotted with the ruins of past settlements and mines, the abandoned project to colonize the surface. The initial investors in Fulcrum Hive had thought to pay for the exorbitant military force required to clear and render the surface of the Zenor of its exceptionally deadly (for the time) wildlife with Fulcrum Factor's proceeds. But as time left them by, they could no longer afford protection, and after their mercenaries left, they lost contact with the surface. The Space Elevator still regularly sends up raw material necessary for the functioning of Fulcrum Hive, but anyone sent down the Space Elevator never returns, and it has been generations since anyone tried. Currently, the main source of consternation for the inhabitants of Fulcrum Hive, was arguments between those who lived in the Hive and those who ran the Factory. Things were heating up, and some feared war might break out again, with the inhabitants turning the salvaged weapons of an era long gone by upon each other.

So, there was a number of reasons Endian might show up to this station. Perhaps she wished to see if the station's "Zenorian XI" metal was any good. Perhaps she wished to beat up on some pirates while waiting for Eos' next orders. Perhaps she wished to test herself against the wildlife of Zenor. Perhaps she wished to establish Eos' order upon the station. Regardless, Miyu was showing up because she was one of those "rogue outfits" who appreciated a space station equipped for resupply that didn't have Eos' attention due to it's lack of machina for Eos to see through.
