A large circular stone structure dominates this room from atop an elevated section of floor. Within its bounds a translucent field of energy shimmers. Through the fields haze the shapes of a far off landscape can barely be seen. Other than the single door in one of the rectangular rooms longer walls six massive stone columns seem to be it's dominating features. Possibly of more interest though are the four big trigger plates in between these columns. They seem to trigger the portals activation and possibly even influence its destination.
