Atavian wings
Constructed from pure white Atavian feathers, the pair of Atavian wings is specially preserved by some unknown magic and fitted with a leather harness which allows them to be worn over other clothing. Once donned, an adventurer can, by uttering the word carved into the harness, bring the wings to life and be spirited high above the clouds, a place from which many other locations on the ground below can be quickly reached.
Like many other artefacts, Atavian wings can be purchased from Merentesh, who has a shop in Delos which specialises in artefact wares.
