Arche

Arche, formally known as Professor Arche, is an NPC from the Eridu Era, and is one of the first seven people to be awarded the title of "Void Hunter". Arche is the founder of Helios Academy and was the discoverer of the common characteristics of Hollows. As such, the Professor is also related to the Helios Research Institute, which holds the copyright to the Hollow Deep Dive System. Information about the Professor is locked behind Inter-Knot's Deep Database's File 0-3092-5800-A6. Before this database was sealed, Professor Arche delved deeper into Hollow Zero in search of the "truth".
