Brotherhood of Frost and Flame

The Brotherhood of Frost and Flame is a group of mages based in the Kingdom of Whytehold. The group was formed to give elemental mages in Whytehold a place to learn without having to go to the Abbey of Metallurgy, or one of the Temples of Light.
The tenets of the Brotherhood are much less restrictive than the alternatives, they simply pledge themselves to the glory of the Kingdom, to protecting its people, and to teaching mastery of the elements to any who seek it.
Knights of the Brotherhood roam the world as mercenaries and heroes, protecting the weak and destroying the wicked (or at least, they try).
The Brotherhood are a much more joyous bunch than most magical orders, reveling in festivities at their great hall. This is partially because one of the original founders was a Thassalian, and encouraged revelry to bond the knights as true companions. Mead is a rather ceremonious drink in the Brotherhood, as all new initiates are given a pint of it to drink, and it is always served at festivals.
Knights of the Brotherhood are very identifiable by their wide-brimmed pointed wizard hats and large plated armour, which originates from an older armour design from the Whytehold Regional Guard (a defunct organisation that protected the countryside of the White Cape, now replaced by the Whytehold Civil Guard). This armour is large and wide, giving those who wear it the appearance of being overweight. The cloth of the knights' tabards, hats, and cloaks are always red, representing the colours of Whytehold. They wear helmets, but the combination of the wide hat and the large armour means their heads are barely visible most of the time.
As their name suggests, the Brotherhood focus on pyromancy and hydromancy, though they readily accept those who wield earth magic or air magic. The Brotherhood is a generally compassionate organisation and do not discriminate against sorcerers or warlocks, even accepting them into the brotherhood if they wish. They are often conflicted with the Witch Hunters.
The Brotherhood uses a ranking system based on the one for the Whytehold Military, though they are not recognised by the Kingdom as an actual military division. They have Soldiers, Knights, Knight-Commanders, and at the top is the Mage-Commander.
The Whytehold military does often recruit battlemages from the Brotherhood, especially those who rank as knights or higher.
Most high-ranking commanders of Whytehold see the Brotherhood as a useless bunch of drunkards and aimless wanderers, irresponsibly flinging spells about. However, Queen Ajelika Weisenburg has a soft spot for them.
The Great Hall in the town of Wintergate serves as the Brotherhood's headquarters, though it is mostly only used for special occasions and for initiations, as most Knights of the Brotherhood are travelers.
