After Seekers rescue Avexis from the blood ceremony, High Seeker Aldren decides to detain Avexis pending further investigation. Questioning the High Seeker's motivation, and suspecting a conspiracy involving members of the Chantry, Byron decides to take Avexis from her holding cell in secret at night. Byron and Avexis escape through the nearby woods with Cassandra following close behind.
Cassandra eventually learns that Avexis is a Circle mage with a gift that allows her to control small creatures. Frenic and his group had kidnapped her from the White Spire. Their blood ceremony was intended to fully awaken her ability, enabling Avexis to influence multiple dragons, even while enthralled under a blood mage's mind control. Frenic succeeds in initiating the dragon flight attack on the Ten Year Gathering until Cassandra, Galyan, and Alte intervene, breaking Frenic's control over Avexis. Now free, Avexis uses her fully awakened ability to direct a dragon against Frenic, allowing Cassandra to deliver the killing blow.Avexis later holds Cassandra's and Galyan's hands as they are honored by the Divine.
- Avexis originally had spoken lines in the movie. However, the director felt that she did better as the strong silent type and her lines were cut.
