The Delrean, Delrian, Derrly Salve, Duran, Olvaladh or Olvalda is a small fir native to cold coniferous forests. It has short silvery green needles which grow in clusters of three and short, fat golden brown cones. Its bark contains a powerful insect repellent, used by rubbing strips of bark onto exposed skin. Unfortunately, the smell is noticeably foul, detectable by Humans at 50'.
