Gladitor is a constellation in the Magiq-verse.
Gladitor is a long, trident-like constellation comprised of one long line, with another perpendicular line on one end and an l-shaped line sticking out of the other end. The image found on the Book of Briars site was white with a blurred, light blue outline.
Gladitor was the name of Fragment Ten. It was found after Aether's livestream, when the word popped up in the video's distortions . The image contained on the fragment page was necessary to solve the third Magimystical Assessment and unlock the Cosmos Key.
During The Day of Change, Deirdre wore glass armor reminiscent of the objects worn by Elainnor, including Durkonos. She used it to defeat The Churning Storm once and for all by striking it with Gladitor.
