Assassin's Creed : The Phantom Guardian

A year has passed after they defeated Pitch, the world was in peace. However the peace was short-lived. After 'Manny' cast a shadow of an unknown enemy on North's workshop, they have to team up with the Inquisitors of heresy, a guardian of the moon, a weird grim-reaper and... a mysterious guardian who seem to be the root of this problem.
