Radiant Feldspar is the Trailblazers' airship in Honkai: Star Rail, gifted to them as a reward for all the trouble they went through to save Penacony. After completing the Cloud-Bound Hearts Adventure Mission, players can have the freedom to change their airship name to Trailblazes Stern, The Tatalov, or The Soaring Clock Hand. Moreover, the Trailblazers' exploration journey on the floating ship will lead them toward multiple collectibles like Treasure chests, Books, and Origami Birds.
