The Fellowship Medallion is worn on a chain around the neck. It is the most noticeable sign of the Fellowship. The Medallions have the form of a triangle, with the letters T, W and U engraved into them (standing for Trust, Worth and Unity, the Triad of Inner Strength). Many are found in Ultima VII. Some react in a hostile manner to the Avatar wearing one (especially Tseramed).
The Trinket Edit
A Fellowship Medallion came as a trinket with the original release of Ultima VII. It looks exactly like the in-game ones, is made of metal and can be worn around the neck with a chain, like the "real" Medallions.
