Lord Reinhart a.k.a. Nick Reinhart a.k.a. Mabus Gaming admitted that the The Dark Below logo was fake and his creation which can be seen on his YouTube channel; the Skysunder logo's authenticity is still in dispute. That said its most fervent defender is ro9ue, and the first I saw said logo leaked was him mentioning if anyone saw the logo "in that other thread." I still haven't found "that other thread", but I've admittedly not looked very hard.
