Lugos

Lugos was a founder of the "Liberalis Circulum", which would later join into the Assassin Order. He was a distant ancestor to Stella Crow.

In the early Roman times, Lugos was carrying the Ankh across the Mediterranean Sea when a waterway accidentally opened, causing the ship to sink. Before it inevitably sank, Lugos recorded a message with the Ankh, detailing the ongoing events.
