Simply one possibility of what could happen if the timeless beings of Atlantis interfered in the events of the Code Geass universe. Will things be changed for better or for worse? Only time will tell. The start of a new venture. Warning: Random crossovers may occur. Loosely based on GURPS Infinite Worlds.
A powerful artifact is stolen from Atlantis, so the Baron, multiversal traveler, goes to the world of AtLA to get it back, and to make some allies along the way. After all, it's only a matter of time before he puts his plan for the multiverse into motion. Or: A timeless being with an agenda of his own joins the Gaang.
