Blue Lichen

Blue Lichen, sometimes called Frost Lichen, is a lichen that commonly covers mountain tops and steep cliffs.

Ecology

The lichen grows in cold and hard to get to places. It is very easy to spot, having a very bright blue colour. The intensity of the colour increases with time. This plant is a dominant portion of a Lichen troll diet. Some animals that enter hibernation for winter also tend to consume it, if they are able to reach it.

Uses

The blue colour of the lichen is often used to make dyes for noble clothing. It is favoured by nobles for a very bright and clear blue fabric. The lichen is also sometimes used by alchemists for various potions tied to sleep and relaxation. Clerics use it in order to open of one's mind as the effects of the pigment can put one into a close to death state.
