Born in 9:15 Dragon in the South Reach alienage to Sarra Ivun and Terys Verlen (birthname, Arauven) of mixed city elf and Dalish heritage. Her mother died in 9:26 of a coughing sickness and her father was murdered after the illness had taken its toll. Meryell was taken in by the alienage hahren and joined a local gang at thirteen to escape (particularly from his rule that she forget everything her father taught her). Members of the gang then trained her as a thief.
Fifteen when the Blight hit Ferelden, she and other members of the gang were hired to aid a pair of mercenaries from the Fangs of Vimmark company for a job. She gained a rapport with the hedgemage of the pair who went by the name Folke and he ended up recruiting her into the company after the job was finished (mostly thanks to her being part of rescuing the pair from the South Reach dungeons).
Meryell has since served amongst the ranks of the Fangs of Vimmark for ten years, gaining regard as one of their best spies over the years. In Cloudreach of 9:41 Dragon, she was chosen as the member to travel to the Conclave in Haven in order to steal a number of rare books during the proceedings. On the 28th day of Cloudreach, the Conclave was destroyed and she became the only survivor.
