You belong to an offshoot of an ancient and recluse race, the Yuki Onna. Yuki Onna are a race of yōkai that can instinctively control supernatural snow and ice that cannot be melted by normal mortal fire. You are particularly powerful, able to wield snow on a scale as to freeze a small town on a moment's notice, and so precise and skilled as to recreate an entire village down to the most minute details with no more effort than blinking. As a side effect all your other powers, if you have any, will rise to match the instinctive control and strength of this if possible. You can continue to grow this over time
A traditionally almost entirely female race, your offshoot seems to have resolved this issue through the result of interactions with humans generations ago, resulting in your population not needing to follow the strange practices that the original race had to make sure they survive. As a result of this you’ve been granted incredible control over the development of your offspring, enabling you to choose whatever they inherit from you and any other parent, whether gender, appearance, disposition, or even powers based on genetics. They will all be perfectly healthy and free of any diseases, genetic or otherwise, and unless you wish it otherwise, will be the most perfect version of themselves they can be. As a bonus this also makes you the perfect parent, granting you the supernatural skill and knowledge on how to make every single right decision in raising them and the ability to follow through with it.
If you wish, you may take a small village of 200 of the same race as you to take as free followers. They will all possess the Yuki Onna power, and if you wish, you may also impart on them any other ability you possess that is a result of a race or species. All members of this village, and any children you have as well, will be perfectly loyal.
