“Titanslayer” is a title given to the top heroic figures of the Anti-Deist army of the War Over Haeven that eventually formed the Sanitorium. Most of these were native to Canath, though they all ended up making their lives in Mogxa after the events of the war. They helped popularise the use of the Idurian Language in Mogxa despite its former connotations as the language of conquerors, due to their folk hero status.
Some of them left behind powerful artefacts and custom spells and rituals they created or honed for the purpose of winning a war against the Gods, which have also sometimes been called “Titanslayers.” These have often been compared to the Remnants, a similar set of items and magic left behind by the Titans before their departure.
