The flower bracelet transmog that we datamined has been found! The Memory of Ysera cosmetic item is a reward from a side-questline found in Ohn’ahran Plains.
The questline begins with Celina Crunchyleaves and Felina Starrunner, a pair of dryads who can be found in a garden near the Green Dragonflight’s ancestral home. They’re worried about Theramus, a Green Dragon and keeper of the garden, who has been struggling with his duties.
