Thomae of Tytalus
Thomae of Tytalus lived from 1122. He vanished in 1198 while piloting a flying castle of his creation, and despite searches no trace of him has been uncovered. Given the legal problems Thomae was facing some have suggested he simply left Mythic Europe.
Thomae is the subject of a chapter of Legends of Hermes. The information above is that generally known to the Order.
