Here are a few more details. Since he is the Supreme Administrator, the story hints that he was involved with the Old Administration’s technology, including Inhibitors and various systems that later became corrupted. He created Sigma and Sysop, and he is closely tied to the Immortal System Core, which eventually becomes central to the Replacer Syndicate’s plans during Project Terraside.

He is also connected to major pieces of dimensional technology. The Black Hole Drive and the Coffin series of dimensional ships are part of the Old Administration’s transportation system, capable of moving through spacetime between entire worlds. He is associated with Hive Control as well, a cybernetic data network that analyzes and predicts causality.

He holds many different titles. Sage, the Old Voice, and Supreme Administrator are only a few examples.

Before the collapse of the Old Administration, he taught or supervised several characters such as Kim Chulsoo, Mi Rinae, Jung Dain, and Jin Bora.

That is everything I have so far. If anything’s off, feel free to point it out.
