The White wizards

The wizards in white are a group of soldiers from some of the northern cities, experts in both defensive and offensive magic. All of them modify parts of their body to be more agile, faster or stronger, and they always wear masks on their faces. They are very resistant to cold despite wearing little clothing and living in places where it is almost always snowing, hence their pale skin tone. This is because wizards in white use cold resistance spells to avoid dying of hypothermia, so they will always have the advantage if attacked.
