Kaine
Kaine opens his eyes with no clear memories. words, past, present, future, all muddled. Three beings surround him: Agamotto, Hogoth, Oshtur. He is to become their agent. They straighten his mind, so he knows the true from the fictitious, the past from the future. However they note this will give him a defense against most mortal telepaths, with such a jumble in his head he barely understands, an outsider would have no chance.
He is returned to Earth, supposedly as he was taken. he takes an inventory of himself. He is in a canadian forest, and directed to make contact with his "brother". Agamotto directs him through his precognative powers. His only posessions are a ratty backpack and an old book written in an incomprehensible language. He simply knows that he feels a sense of loving jealousy toward the author. She had something in common with him.
Basically it's Kaine getting jerked around by the Vishanti, and exploring parts of the Marvel universe that aren't seen enough. In New York Kaine discovers that along with MJ, and other facts, the Clone Saga has been removed from Peter's memory (as well as everyone else). It is discovered that while Mephisto can re-write, edit, and change, he cannot destroy. Thus Kaine exists. Kaine believes his job is now to force Mephisto to undo his changes. He asks how to get to Mephisto's realm, and is directed to Los Angeles to find "She Who Walks Between the Realm of the Living and the Realms of the dead". She will be found with "He who rebounds", but they can only pinpoint "He who rebounds". Basically he has to find the Slingers who livin in L.A. because Cassie can get to Mephisto's realm, and she's shadowing Johnny.
ON his way there he has a flashback, remembering where he got the backpack. In Kentucky he passed out from exhaustion and hunger. Michael Van Patrick found him and brought him to the family farm. They nursed Kaine back to health, and they gave him one of Michael's old backpacks. Kaine moved on, but not before giving the sixteen year old boy a prophesy. He would either mary a beautiful woman and together they would bring up the world's next great hero, or die violently and horribly.
In Los Angeles he gets Cassie to reveal herself by owning the Loners/Excelsior and threatening Johnny. Cassie shows up and his true purpose is revealed: Eddie's death was manipulated by Mephisto, so that Eddie's soul could be stolen. Cassie must take Kaine to Mephisto's realm to do battle for Eddie's soul.
