I wish I had a PC because of all the stuff you can do on it. Console commands, mods, ect.
I doubt that it came through a portal, because the portal had to of been up about a mile in the air. When I first saw the thumpers, I thought that they were new citadels. I just think that they normally builded it. But, with all of their advanced tecnology, It was built much faster...
