Below is a walkthrough for the Payback for Treason hero quest in Xenoblade Chronicles 3. To obtain this quest, complete the Lovebirds quest then approach the ? in the residential quarters of the City.
For the first task, fast travel to the Eternal Canopy landmark on Daedal Isle in Cadensia Region and rope slide to the center part of the island. Once there, make your way to the objective being mindful of all the high level enemies in this area! To reach the objective, you’ll need to swim through the water on the northeastern side to find a cave. Head through the cave then climb up the purple vines to reach an open area. Run across this plain then jump down onto the plain below to find the objective. Once you reach it, a cutscene will trigger followed by a fight with 5 Level 51 Hardliners. Defeat them then return to the City by fast traveling to the Astelle Harbor landmark in the center of the area. Approach the objective to trigger a cutscene.
After the cutscene, you’ll need to acquire 3 pieces of information regarding the Rozana’s Whereabouts topic. First, speak with Drumdrum on the east side of the City. Next, speak with Clara and Hollis in the southeastern corner of the City. Upon acquiring all 3 of the pieces, head to a rest spot and discuss Rozana’s Whereabouts.
When the cutscene concludes, fast travel to The Swordface in Cadensia Region and make your way north to the objective to trigger a cutscene. Head down the passage and open the door at the end to trigger a cutscene followed by a fight against a Level 52 Evolved Sentry. Defeat it then you’ll fight Level 51 / 52 Hardliners. After you defeat this group, the quest will complete!
