A species that debuted as an adopt I made (With one still for sale) The Harpier is a bipedal avian sapient beast from D2.

They resemble harpies, by ways that they aren't hexapodal like 'angels' and other animals that have wings on their backs, such as western dragons and gryphons. They have clawed hands, with wings that attach like those in avian and non-avian theropod dinosaurs.

They are highly intelligent, capable of speech and emotion, and manipulate things using their beak, wing's claws, and feet.
Harpiers are capable of powered flight, due to being very lightweight and their arms and chest being rigged with powerful muscle.
