The Wolf and The Light That Remade It
When a wandering Ghost had decided to comb through the European Dead Zone in search of Guardian prospects worthy of The Traveler's blessings, it hadn't expected to stumble upon the remains of a stranger from another universe. A quick scan gives it all the information it ever really needs know, and the Ghost, having finally found a Guardian to call it's own begins the process of "Waking him up" as it were.
Hopefully that giant sword of his wasn't just for show, cause those Fallen over yonder sure looked angry as hell, and it didn't exactly have enough power left in itself to do much besides revive him.
Post Advent Children Cloud winds up in the Destiny universe dead as hell and replaces the Young Wolf as protagonist, losing both his connection to the Lifestream and memories in the process.
