The innermost levels of planet Griyadin contain some of the Cybers' most ancient and powerful secrets. Existing near the world's very core is the so-called "Heaven and Hell Department", which has long toiled to study and harness the awe-inspiring powers of angelic and demonic magic. The former-neraphine Cyber known as Halcyon is one of the leaders behind many of these projects, and is sometimes treated as the de-facto leader of the whole department (to the chagrin of those in the Hell Division). Notably, she's directly responsible for the creation of multiple Salvaged Angels such as Cheri and Ophelia, and was instrumental in both the reactivation of Aekros and in the creation of Exgal.
The secrets of angelic magic are largely lost to history after the fall of Caelestian civilization, over 4000 years ago. The planet Syndomera has been rendered a barren inhospitable wasteland, the remnants of its magi-technical wonders left moldering under acidic skies and bubbling muck. The neraphines who survived the fall made a floating city their home, and ever since then there has been a strong stigma against anyone studying the machines that destroyed the old world.
A few centuries ago, the neraphine entanma who would one day become Halcyon, rebelled against these taboos. She began amassing lost knowledge and relics of ancient Syndomera, becoming a sharply divisive figure; broadly reviled by many as a heretic who was tampering with dangerous weapons that should have remained buried, while also gaining renown to some as a wise scholar of ancient sciences and history.
While her ideas had been considered dangerous in her time, she became much more dangerous after being assimilated by The Cybers. Before converting Halcyon, The Cybers had long been struggling to replicate or control caelestian artifacts directly; their best efforts could usually only produce new designs that imitated some aspects of the ancient neraphine magic, such as the Gehligrukai line, and the Astral weapons. While formidable, these creations fell short of any true understanding of caelestis's power.
Halcyon has changed this. With the expertise of her prior life at their disposal, the Heaven and Hell department has slowly begun to unravel some of the ancient caelestians' secrets, giving rise to some of the Cybers' most dangerous and terrifying creations. Now, even angels of yore are being reawakened to serve them...
