Kmeser Tree
The Kmeser tree is the sole source of the valuable Leukos jelly and is a curious plant in general. The Kmeser is a partial parasite - it can gather most of its nutrients itself and survive but it only truly thrives (and produces Leukos) when it has a host tree to feed from. The Kmeser tree is a fruiting "tree"/plant - it frequently produces fruits to attract animals to eat them and spread its seeds. To bring in pollinators, the Kmeser produces vibrantly colored flowers. The flowers, known as Kamara flowers, are highly prized by people in the Kingdom as a sign of beauty, love and prestige.
The flowers themselves are well known to be hard to get due to the fact that the tree is only really found in wild, undeveloped land. In particular, the Kmeser prefers humid and water-logged areas (i.e., swamps and jungles most commonly found in distant regions of Enxe and the Southlands). The tree has proven difficult to properly domesticate and grow away from its preferred environments. The flowers are noticeably less colorful, vibrant and elaborate when the tree is not parasitizing a host and no Leukos of any value is made without a host. The tree grows slower in drier climates as well. As such, only a handful of Kmeser plantations exist and these are under the iron grip of the Royal government. The majority of Kmesers as such are found out in the wild. The tree seems to avoid settled areas (likely due to a lack of preferential or extant host trees to parasitize) and this has lead to the formalization of a profession to chart out the locations of such trees, the aptly named Kmeser Seeker (or Kmeser Hunter).
The Kmeser's fruit and leaves are quite edible and so provide a useful food source for wild animals. The herbivores then attract the main predator that lurks near the Kmeser, the Krensar wolf.
