Known for the gleaming blue colour of the leaves, the tree often grows in thick copses throughout the north. The thin trunks of the trees are remarkably durable, despite high winds and heavy snowfall. High-priced entertainers often burn small pieces of wood, which creates leaping blue flames. The leaves and sap are often ground in the creation of a vivid blue dye that is used to dye clothes in the North, and often in the creation of inks for tattoos. One group of Langækur that has plagued the Reynessen coast in recent years is notorious for their crews bearing frightening-looking blue tattoos covering their faces.
