Ytri/ol was a male Trinni/ek who served as Speaker, or the head of government, of the Trinni/ek people. The United Federation of Planets made first contact with his world in late 2379 or early 2380, and in the months that followed, Ytri/ol worked closely with Federation Diplomatic Corps Ambassador Colton Morrow to lay the groundwork for opening diplomatic relations. In May of that year, he and a party of Trinni/ek representatives travelled to Earth to meet Federation President Nanietta Bacco and address the Federation Council. However, Ytri/ol and his party feel inexplicibly ill after leaving their home system, and at a formal dinner held at the Palais de la Concorde, broke into a paranoid outburst and abruptly left Earth.
