There are many different types and variations of wings you can collect within Revelation Online. For example, there're robotic wings, wings made of flames, butterfly wings, and angel wings. Some wings are exclusive to certain vendors and factions while the others can be gained by combining wings together.
There's a Black Market in Revelation Online where you can purchase Starlight Dragonfly Wings by obtaining 12 different Dragonfly Fragments. There are also dungeons in Revelation Online which offer you a chance to obtain a wide range of wing crafting materials. Apart from that, if you can get Fine Feathers, you will be able to combine and advance wings.
