Infinity [Poki/Perloki] (PJO/Avengers)
Before fading, Chaos created 6 beings (all women) to help withhold peace amongst the realms and universes. From oldest to youngest, their names are: Time, Space, Power, Soul, Mind, and Reality.
Thanos is a being who is trying to find all of their Infinity Gems, which are their symbols of power. In an attempt to save the universes from such an evil, they call upon the man who was lost to Time - in more ways than one.
