In a sense, you could say Gaspar guided most of the events of Trigger, much like Belthasar is the mastermind behind the plot of Chrono Cross. When will Melchior get his turn?
Hmmmm, maybe, if Chrono Break ever does come into existence, it will be the final episode in the trilogy, with Melchior (Guru of Life/Wisdom) finally healing the universe after it's been warped, rewritten, and splintered who knows how many times. It would be appropriate for the Guru of Life to finish out the story, finally bringing healing to the world.
