Amaranthine deodar, sometimes called “ghost trees”, is a type of tree, harvested most prominently on the island of Leovigild, that remains alive (and therefore connected to the Loom) even after being harvested. The deeply colored, reddish-purple wood is often used in the construction of enchanted items, most commonly as the focus pieces for gnostic sorcery to allow them to more easily peer into the Loom. After being cut, it will continue to sprout new branches as long as it has access to water and air unless enchanted appropriately.
Ghost trees grow from acorns that are ritually planted in the bodies of dead elves. The elvish funeral tradition is to bring the corpse into the forest, split open the dead’s chest, and place an acorn of the amaranthine deodar where the heart is. The heart itself is removed and cremated. Most forests of ghost trees are actually graveyards. Sometimes the living trees are carved into the form of the dead buried there. This was most often done for the graves of dead warriors.
