My Titan didn't die. He's still dead. The experiences he cognitively saw was all a vision from The Traveler shown to him while his light dwells in limbo. A vision of the journey to come. The last words he heard from The Traveler after the glorious vision ended was "in a months time, your true journey begins. Sleep well, Guardian. It'll be the last true rest you'll have for a long time." He now waits for his Ghost to bring him back to this world...this time, for real.
