Avalan Outpost is an environment designed for the game design project Lilyveil. 

Here is the description from the Lilyveil artbook:

Avalan Outpost is a small village located high in the icy mountains, away from prying eyes. The residents are hardy and cold, as they have to be to survive in the hostile conditions. The people are protected by spirits, having a strong bond with the world’s hidden magical forces. It is rumored that this is where the legendary “Fountain of Immortality” is hidden.
