The Librarian (EntityTopic, 13)
From Compile Worlds
The Librarian is a nameless(?) librarian who works in a library within The Abyss in Compile Worlds. His one and only appearance was in Episode 20, where he fired his Shadow Cannon™ on Draco Centauros after she offended him with her disdain for black magic. He was accidentally murdered by Lagnus the Brave moments later, who was only trying to defend Draco and shut off the Shadow Cannon™.
