I thought about Heroic Age's plot presented so far and I've come to a conclusion: the Gold Tribe are made of retarded/insane guys!
Why? Well in episode 3 it's told that the Nodosses were transformed into gems because the Gold Tribe found them guilty of destroying several civilizations and so they punished the five remaming Nodosses. So why in the hell:
1) they accepted Nazi-like labours from the Iron Tribe and, most likely, from the Silver Tribe as well?
2) did they give
four Nodosses to the already strong Silver Tribe?
3) did they give the four Nodosses foreseeing what would have happend as they can predict the future?
4) didn't they punish the Silver Tribe as they're doing the very same thing of the Heroic Tribe?
