I'm talking, for example, about this: http://he-man.wikia.com/wiki/Snake_Clan. The Snake Clan is only in one Filmation episode and only a little of the entries content is from there. There are no sources for the other stuff mentioned and I don't find any when searching the web. It seems completely made up. This continues here: http://he-man.wikia.com/wiki/King_Jarod and here http://he-man.wikia.com/wiki/Government_of_Eternia as well as in several other connected entries.
