Introduction
Trammel is a facet, or "map," within UO.
Trammel is a mirror of Felucca, UO's original map, except that non-consensual PvP is not allowed. It has also not been allowed in UO's subsequent facets. Facets whose rules do not allow for non-consensual PvP have come to be called "Trammel Rules Facets." (Example: "Malas is a Trammel Rules Set Facet.")
The fiction of Trammel is that it was created by Nystul, the court mage of Lord British, in order so that Britannians could have a place to live that was free from the ravages of Minax, who was, in addition to the PKer/murderer problem, attacking Britannia at the time (especially the City of Trinsic).
