The Journey's of an uninterested person

A man, immortal yet not, never aging, never ending. A victim of deaths callous rejection, stuck in time, until the end of the world only to repeat for eternity. is given a chance, a gift to enter a new world, a new universe, an escape from the limits of his world. Knowledge is his passion
no, his drive
after losing it all far too many times
what can a man who has seen everything do in a universe dominated by beings whose emotions are their reasons to live.
what can a man who finds cruelty and kindness equally the same in his jaded view do?
