   Summary

   Tartarus has a simple plan of attack: amass a giant army of as many monsters as he can make, revive his children, enlist the help of other major villains, and a launch a single, overwhelming, surprise attack that leaves the heroes utterly destroyed. No war, no ceremony, just carnage and death. Too bad for him that Chaos decides to get involved and make a game out of it.
