Years ago(after season6 episode2)...
Martin stared up ahead and saw that he was now in space."Crazy kid,telling me he's my son even though I never saw him before",Martin told himself while he and his band of ancients were venturing into a void that the void caster (well duh :P) created in an attempt to escape from the crystal citadel. "Hey what's in this void anyway?",Martin asked the void caster,an entity with spikes where its face should be, the void caster just simply pointed to what appeared to be another crystal citadel. I knew there was a crystal citadel but I didn't know there were two,Martin thought to himself while they floated closer to the crystal citadel. Once they were now right in front of it,all of Martin's companions immediately jumped off and landed on the crystal citadel,"Wait,were you all going!?",Martin yelled after the jumped onto the citadel and started running after one ancient after another."Hey,we can't keep destroying stuff wait for me to think of what to do next!",Martin yelled after the ancients."Hey-AAAHHH!" Martin yelled because a crystal suddenly landed right in front of him. Martin noticed that there was a writing carved onto the crystal,"This citadel was constructed as a prison for those who have committed cosmic crimes so horrible that they can't be uttered. This citadel also serves as a spare citadel in case the original citadel has been either one or both citadels be destroyed,the ones who destroyed it will be punished,punishment for destruction of one citadel will be so horrible that it also can't be uttered ,but punishment for destruction of BOTH CITADELS will be nothing else but...DEATH!",Martin read from the crystal. "Void caster!",Martin called out and the said ancient immediately appeared in front of Martin,"We have to leave and stop destroying this citadel or else...",Martin's sentence was cut short because the void caster pointed to what appeared to be another crystal prison still stuck to the ceiling and the prisoner still inside...
