In March, she unexpectadly withdrew from the race and put her support behind Councillor Anlenthoris ch'Vhendreni.

In 2165, T'Nol sent Raldul alignment operative Temos to TesKahr Central Hospital to falsify First Minister Kuvak's birth records in an attempt to discredit him by making him appear a Human infiltrator. The plot failed, when Temos was captures by Starfleet and local police, and he made a confession. After this failure, Dular Garos cut all ties with T'Nol's now ruined organization. Not long after this, she was contacted by former Administrator V'Las to help him carry out a coup.
