You can claim rewards by finding all 20 Origami Birds in The Reverie (Dreamscape), one of the more complex Dreamscapes in Honkai: Star Rail's Penacony. Navigate through hidden rooms in the maze-like area to coerce the mischievous birds back to Lady Vermillion.
Honkai Star Rail The Reverie Dreamscape All Origami Bird Locations (Origami Bird)
Origami birds always get stuck in the strangest places. If you want to find everyone in the nest, we've got you covered.
Vermillion Birds are scattered throughout The Reverie (Dreamscape), an area that unlocks as you progress through Penacony's Trailblaze Missions. I highly recommend finishing the story before starting the quest, as the rooms unlock gradually. As with the previous areas, you can find the Origami Birds in any order.
Go to the area circled above in the northeast room in The Reverie (Dreamscape) F3 to find an Origami Bird stuck in the fireplace. Pull it off to save the Worried Bird.
