You and Moondrop had met once in the past, it was a very unpleasant encounter. You were basically the ‘evil’ version of the ‘original self’ and a lot like ‘Lord Eclipse’, you rested your world with the star

He didn’t want to go back to that dimension, yet again, he HAD to know how his Eclipse came back. ‘Lord Eclipse’ didn’t answer all his questions and Moon knew if anyone else would know how… it would probably be you

So, he hopped into the portal and was teleported to your world
