Hypothetical I've been thinking of, what locations and people would be in a Ninjago White Space

I've been trying to theory craft an idea for a Ninjago generations storyline. I was thinking the two areas of white space would be for Lloyd and Garmadon (Lloyd being on a more linear White Space like what happens in Sonic Generations and Garmadon in a more open one like Shadow). My current thought was having the time twins be the main villains of Lloyd's White Space and the Overlord for Garmadon. With that in mind, who and where would you pick for each area submitted by /u/luckyblock98...
