"The Source, if I'm understanding it correctly, is a story about the Alphans-who are the ancestors of humans? (I've never been clear on this point)-leaving their world for a new one (hint: Planet Y) because a rogue AI has decided that the best way to cope with planet's problems is to kill everyone. This sets the stage for an epic musical journey in four parts, with the individuals discovering the problem (Chronicle 1: The Frame), leaving the world (Chronicle 2: The Aligning of the Ten), getting to the new world and getting injected with Liquid Eternity (Chronicle 3: The Transmigration), and the last one, which I won't spoil (Chronicle 4: The Rebirth)".
