AU where a group of dark fey, led by Connel, visit the Moors sometime during Aurora’s childhood. They are saddened by the darkness and shocked at the evil grounded fey they find.

Look at my last post with this title for the premise. Basically Udo, after looking for the missing fey for some time (because the non captured fey have no idea what happened) finally finds the Isle of the Lost and enters it using a portal that works so only he can go back and forth. He’s horrified by the conditions. Starving children, children without shoes in a biome that definitely requires shoes, fey children with clipped wings, etc. He comes across Borra who takes him aside and explains everything. Long story short, Udo becomes a sort of mail man to and from the isle.
