Where to Find the Litamiotvitr Cairn
This mystery can be found on the southernmost island in Asgard, facing southeast toward the world tree Yggdrasil, as shown on the map below.
This is a fairly standard cairn mystery, for which you’ll need to stack the stones to the required height and then “validate” the positioning. You can do this in any order that you want, but you’ll find it easiest by starting with stacking the larger stones at the bottom first. Once the stones are above the threshold, validate the cairn to complete the mystery, earning you +1 Skill Point.
