Wiki: "You must go into its nest with a fast bird, steal an egg, run away from 50+ wyverns trying to kill you, go back, get a female wyvern, knock it out, get its milk to feed your baby wyvern, raise your baby wyvern for many real life days, never sleep, starve, make sure you got lots of milk, get arthritis, play non-stop, never see society again, boom you have yourself a wyvern."
