Fan Casting Guardians of the Galaxy: Mirror of the Soul

While on a mission to retrieve an extraordinary creature for Lady Hellbender, the Guardians come across an old man, stranded on an abandoned planet. He claims to be a former priest for the Universal Church of Truth, seeking peace and harmony through their religion, and who's carrying a mystical yellow gem. After taking him along with them, they get taken in by the Nova Corpse for their illegal trading deal. Throughout the film it becomes clear they're being hunted by several parties looking to obtain the gem from them. As they escape the Nova Corpse facilities and flee to evade their hunters, they eventually cross paths with a man by the name of Adam Warlock. He reveals that he is the original 'god' of the Church, and that they now worship the Magus, a dark part of himself. He aids them in keeping the Soul Stone safe, and defeating the evil plans of the Universal Church of Truth and the Magus once and for all.
