The Delrean, Delrían, Derrly Salve, Dúran, Olvaladh or Olvalda was a small fir native to cold coniferous forests. It had short silvery green needles which grew in clusters of three and short, fat golden brown cones. Its bark contained a powerful insect repellent, used by rubbing strips of bark onto exposed skin. Unfortunately, the smell was noticeably foul, detectable by mortals at 50'.
