You walk over to it, and Luna follows you. “This is part of the system Twilight and I are building to give pegasi the ability to fly again, if something happens to their wings.” You reach it and crouch beside it, propping it up so it’s oriented vertically. It suffered no damage from its gentle fall. “These three blades here spin, like three thin wings. The whole thing works a little like a big fan, you could say. We’re going to have one on each side of what you could consider prosthetic wings. They’ll generate enough thrust to get the pegasus off the ground and, once they’re tilted in the right direction, on their way.”
