The Jewels of Cyttorak

"Juggernaut is on a rampage!" Since bonding with the ruby of Cyttorak, Cain Marko became the unstoppable force known as the Juggernaut-and one of the X-Men's most vicious foes! But an archeological dig reveals a fragment of the one thing that might be able to stop the Juggernaut: an emerald from the same lost city of Cyttorak. Now a ruthless billionaire named Service intends to gather all the fragments of the emerald, which will grant him absolute power-unless the X-Men stop him. If that wasn't bad enough, each use of the emerald causes the Juggernaut pain...and he won't stand for it!
