Thank you, Skry! : ) That's absolutely brilliant! I'm really curious about the Vex now, and what the Stranger knows! Your theory also fits so well with the heart of the black garden, I just can't seem to piece it together... It seemed like the heart was in a pocket of time and space, on Mercury. And when we destroyed it, the pocket collapsed as well! The heart was also draining the traveller's power, or so we're told. But maybe that wasn't it's purpose, but a necessity for something else. And somebody or something turned Mercury into a giant machine... Could the heart have been their attempt to transcend time and space?
