This episode is actually presented in a flashback-style format, as Fergus tells the story around a campfire to a group of children.
Title: The Spear of Destiny
The Spear of Destiny was said to have been used by Loginus to stab Christ in the side. It has been said that possession of the spear would give one the power to conquer the world. The fact that at the end of the episode Loginus decides to no longer try to remake the world in his image while in possession of the spear is almost contradictory.
