The Twin City Opera House has two open portals. One portal is located in the Catwalk next to Roberts wine, and the other is located in the sub-basement, coming out of the entrance to the original tunnels. The portals make the Opera House activity change from day to day. Many gifted people compare the tunnels to a train station. People come in to the station, hang around for a little while, then get on another train and leave. It is the same with the Spirits. One day there may be one Traveler at the Opera House, other days that number may change. Some nights there is light an friendly feel, and others it seems darker and more foreboding. We never know waht to expect until we get to the Opera House.
