Koselia, maiden of the mountains

Koselia is a majestic and powerful goddess who watches over the frozen peaks and valleys of the Mountains. As the embodiment of winter's might and the guardian of all things frosty, she is both revered and well-loved by those who dwell in her domain. Her presence is marked by swirling snowstorms and icy gusts of wind that can freeze even the hardiest of adventurers.

 As the goddess of the frosty mountains, Koselia wields power over ice, cold, and snow. Her influence can be felt in the biting winds that cut through the tallest cliffs and the treacherous ice that covers the mountain paths. She is a patron to those who she deems worthy enough to protect her domain, offering power and knowledge in exchange for allegiance, but only rarely. It is considered a great blessing by the mountain inhabitants to be chosen by her and only a few individuals are ever chosen in most peoples lifetimes.

Although her presence can often be felt in the harsh icy winds and fleeting snowstorms, most of her followers do not know much about her other than stories from generations ago. They often tell of her intense otherworldly beauty and and guardian frost spirits who are always at her side.

Koselia is a wise and knowledgeable being but asks for the utmost seriousness and devotion from those whom she shares her gifts with. She detests those who abuse their power and cause unnecessary suffering or to bring imbalance to the natural world. Her warlock followers are expected to be the protectors of the natural world and its delicate balance, defending the frosty mountains and its inhabitants from those who seek to exploit or defile them.
