(click to go through) For a long time, Unnamian elements beyond the main 5 were considered to be limited to at most one per monster (and they often were, due to timelines and blah blah blah). However, that all changed when a particular group of monsters was conjured through a strange experiment: the Mistraterrestials. Due to them containing two "extra" Unnamian elements, they are more unstable entities than other Unnamians. You can make concepts for the undiscovered Mistraterrestrials if you want. Don't be mad if they don't become official, though.
