I spent quite a while going through the blue terminal, but I couldn't find what you were talking about. Since you turn around so much in this game, I couldn't tell where north was. I thoroughly searched all tower like structures but found nothing. Just went in circles, occasionally finding the entrance again and collecting ego orbs.
Can you give me any more clues? Or is there some other condition to making this secret appear? Is it a different portal, a strange coloured ego orb, a special sound cue, a hidden area or something else entirely? I feel lost. Sorry.
