Glyph

Auteur once attempted to ritually ensure his survival by writing a message in "abstruse glyphs that began to turn and interlock like gears the moment he was done writing them". (PROSE: Resurrection of the Author)

Behind the scenes
The "glyphs" in Resurrection of the Author match the description of "Circular Gallifreyan", a writing system which Auteur was also implied to use in Going Once, Going Twice.
