As far As I can remember it was UO "Second Age" and they added nothing to the system other then some green and red rocks that looked like eggs, you would click the rocks and they would open a gate to either the Trammel or Fel facets,,, I don't think they even had trammel on the public gate until about 3 months after with an updated patch,, only way you could change facets was with those dang hard to find rocks,,, also reds were able to travel to trammel but it made them turn blue ,,,<--- that was a bug they fixed very quickly, and made it were reds could not even travel there...
I may not be completely accurate ,, but I was playing hard core everyday about 12 hours a day back then,, so my memory is pretty good about it , well the cells I didn't burn out can remember ,,the ones that did burn are just gone ,lol
