Speed

Ryu's gaze landed on a delicate pair of wings that could fit in his two palms. Its feathers were entirely transparent and even looked quite silky to just his eyes alone, but with it, there were delicate vein patterns pulsing with silvery energy. 

The pair sat within a glass encasement, separating them from the world and making them seem as though they were an uncountable distance away. Just below this glass case and at the start of the pedestal it sat upon was a name plate. 

Quivering Spectral Wings. 

There wasn't a hint of explanation beyond this, but Ryu could sense that the name held weight. As he gazed at it more deeply, he began to feel his completed Dao stir and he realized something. This wasn't an overt test, but it was a test nonetheless.
