Mordreda has long been the nemesis of the Archeos and is now determined to strip them of their powers, and close the Star Gate portals to their powers forever. Her only avenue to success is through Scarpio and The Scepter. She can get Scarpio all the powers he wishes from the dark force through The Scepter but any power he might want must come from his mind, and the solution to stripping the Archeos of their powers must come from him too. Sam, Yoder and Mike, aka the Archeos, find themselves in a fight to the finish and it brings them to the brink of their own destruction. The Scepter opens a portal to the occult plane for Scarpio and there he finds worlds with dark force powers that boggle the mind. He must now find a way to lure the trio of cousins and their new partners into one of those worlds where he'll have them under his complete control. He finds a way alright and it's one that makes the Archeo's follow him there without hesitation. The Archeos have added their grandfather, and Jack Crawford, to their team. That means all 5 of them are facing death if Scarpio can get them to reveal the locations of the Star Gates. The evil Mordreda is staking her very existence on Scarpio finding those locations. If they're destroyed that will open the door for her to return to earth and take control of The Scepter, then the powers of the dark force will be hers to command.
