Once Elyriel settled into life in Trinsic, she had very little desire to go anywhere else. She obtained her citizenship after the requisite time period, and for a goodly while she was content to live, plan her wedding to Wraith, and defend the city when called upon. Aside from her carefree days back at Stark, this was the best time of her life.
Trinsic as a city had a history of trouble, though, and becoming stationary just meant that trouble came to Elyriel.
