Kanin—one of the most powerful of the five troll tribes. They are considered quiet and dogmatic. They are known for their ability to blend in, and, like chameleons, their skin can change color to help them blend in to their surroundings. Like the Trylle, they still practice changelings, but not nearly as frequently. Only one in ten of their offspring are left as changelings. The Kanin are also the oldest tribe of trolls, having been the original troll tribe before the brothers Norund the Younger and Jorund the Elder fought about moving south in circa 1200 CE. Norund stayed in the north, strengthening the Kanin in Doldastam, while his brother went south and established the Vittra in Ondarike.

Karelian Piiraka—a Finnish rye pastry. Rye-crusted, handheld pies with rice porridge as the most common filling, but a mix of root vegetables as filling is a frequent variation.

kasteren axe—a small hatchet with curved blades, similar to an ulu knife, with a long, slender handle. Used in the game of økkspill. The name means “thrower.”

Kebnekaise—the highest mountain in Sweden. The Kebnekaise massif, which is part of the Scandinavian Mountains, has two main peaks, of which the southern, glaciated one is highest at 2,097.5 meters (6,882 feet) above sea level as of August 2014. The mountain is in Swedish Lapland, about 150 kilometers (93 miles) north of the Arctic Circle.

klampiveleska—an álfar term for spouse or life partner; the literal translation is “the one you fondly choose to be joined with.”

Lake Sodalen—an elongated mountain lake in the valley of the Kiruna municipality in the Swedish Lapland. In summer, boat traffic runs on the lake. The name means “valley lake.”

leat fámus—an incantation meaning “to be open” in Irytakki.

Lost Bridge of Dimma—a legendary bridge in troll mythology—akin to the city of Atlantis or the Hanging Gardens of Babylon—that is watched over by the Älvolk. The bridge was alleged to have connected the ancient troll city Áibmoráigi to the utopian kingdom of Alfheim, and it was believed to have collapsed before the end of the Viking Age (circa 1000 CE). The bridge was lost and the First City of Áibmoráigi was destroyed during the Battle for the Bridge, also known as Vígríðabifröst.

lysa—a telekinetic ability related to astral projection that allows one troll to psychically enter another troll’s thoughts through a vision, usually a dream.
