So, last night, I help some people with a coffer. We farm up the key, we search for the coffer. Eventually, I go check the spawn point that requires you to go through the Glacier to reach. Well, I find it there, so eventually, we get Legult his Old Gauntlets. As we're leaving, I snap the following screenshot:
I didn't realize I was taking a picture right as we're zoning. I don't know if it's this way for PC gamers, but for xbox and ps2, when you snap a picture, your console locks up for a second. Well, it just so happens, I locked up at the zone line, and this caused me to skip it. Whilst my party members found themselves in Batallia, I found myself somewhere entirely different.
At the end of the stairs, I found a gateway... to... nothingness. That's right. A portal if you will. Here are the pictures:
I noticed that through this gateway to another dimension, I could actually see back into other sections of reality, as evidenced by the last picture above. I contemplated entering this gateway, although I felt a force keeping me from doing so. In the end, I opted to return the way I came. I'll leave the exploration of the unknown to more scientific minds.
