Bound by fate
read it on AO3 at https://ift.tt/MWV2A51 by Yanira In a universe that faithfully follows the lore of Supernatural, Dean Winchester, Sam, and Castiel confront an ancient creature known as the Primordial Shifter, which alters human biology by imposing a secondary gender: alpha, beta, or omega. The curse transforms Dean into an omega, Castiel into an alpha, and leaves Sam as a neutral beta. What begins as a biological crisis filled with intense scents, uncontrollable instincts, and an increasingly devastating heat cycle slowly becomes the discovery that Dean and Castiel are destined mates.
