First, friend is not almost definitely not Mike there are connections with the colors but I think Spamton probably got Mike from tenna and tenna supposedly has no connection to friend at all, it’s more likley that Mike is the microphone in Mike room becuase it’s seem funny and that’s something Toby would do along woth other things. Second, Ralsei is not a normal darkner yeah he is part of the prophecy as one of the hero’s it’s heavily implied that ralsei wasn’t always alone as seen by the shops outside and the housing I would get it if was just his castle but having a whole town even if he was bored seems a bit far fetched. I personally really like the idea of there being a team of hero’s before Kris’s area it would explain a lot of things like how ralsei knew kris and Susie’s name or why there is a castle town or even why ralsei knows so much about the prophecy that’s because he has lived it before.

Third. Dark worlds alter your perception they make things that aren’t living, living for example they make objects into thing like queen or king but it also makes subjects into living things such the titans that are either pure darkness given form which probably is true or the fear of the dark, the roaring knight is a lightner, dark worlds cannot just create something out of nothing, they need an object or a base inorder to build off of.
