Although only two of the orders are really touched upon in the novel, there are four orders of the church in the Gauntlet Series. I have pages and pages written about each of them, but here are some snippets. The church itself accepts, trains, and sends out members of each of the four orders, all of which have headquarters in Kaneelis.
Order of Might
Primarily composed of high-born sons of the nobility, this militaristic order is made up of five Brotherhoods, each attached to the countries containing a seat of power for the church. The primary Brotherhood is in the capitol city of Kaneelis, in Terris, of course, where the Brotherhood of the Shield oversees affairs for the city as well as the rest of the church. Each member of the brotherhood first trains as pages, then squires and scribes, then monks and warriors, and finally as knight-priests. They are generally free to choose their calling, whether as palace guards, personal trainers and teachers, assistants to the bishops, church staff members, or fulfilling personal quests in the name of Adona.
In Falara, the Brotherhood of the Lance works as the city guard, as well as training and leading the secular militia in defense of the country and protecting citizen and guarding the border from the Redolian menace.
The Brotherhood of the Sword, in Silver, attempts to stay out of the politics of thirteen warring brothers while trying to maintain order. Theirs is the most difficult order and the bishops stay in constant contact with the church in Terris, seeking guidance.
In Bodor, the Brotherhood of the Ring has spent decades in the service of an aging king, far from the influences of the primary church in Terris. It is feared that they are losing their way and communications with Terris have been growing strained.
The Brotherhood of the Gauntlet, in Ven-Kerrick, have held the honor of guarding the gauntlet–or perhaps guarding those who would lose their lives attempting to steal it. Each Gauntlet Knight has been hand chosen by the Ven-Kerrick king, based on their qualities of honesty, integrity, intelligence, and sometimes things that only the king can see.
Order of Knowledge
There are three branches of the Order of Knowledge. The Brotherhood of the Book are the keepers of knowledge and maintain extensive libraries in all major cities. The archbishop is always chosen from the Brotherhood of the Book.
The League of the Pen contains scribes and is one of the few that accept women. There is no priesthood and they are often sent to work for overlords with a monetary agreement.
The Brotherhood of the Path is for wandering priests. There are several fixed sees and monasteries that are up-kept by mandatory one year indoor service contracts. They are the most numerous of the orders and can be found speaking the word of Adona even in heathen countries such as Redol, Akarska, and Tar-Tan.
Order of Healing
Healers are the most respected and the most desired members of the church. They are found in nearly all cities and often share space with the Order of Knowledge. There are three branches of the order:
Brotherhood of the Leaf: Mostly found in the northern countries, Terris and Falara.
Brotherhood of the Chalice: Occupies the countries south of the Abyss: Penkangum, Silver, and Bodor.
League of the Rose: They allow both women and marriage, a rarity in the more bookish orders, but they claim that celibacy is unhealthy and women tend to be more compassionate healers.
The Bardic Order
Bards are not priests, or even monks, and women can not only be members, but also ministers. Usually found where there are healers, the teaching center is only in Kaneelis. Bards wander the world from there. Anyone may become a bard, and they are designated by the wearing of blue robes with a badge upon their breast, as follows: White Palm (for song), Golden Harp (for harp), Brown Lute (for stringed instruments), Green Pipes (wind instruments). Each foil is awarded upon completion of Mastery, therefore Bards are referred to as unifoil, bifoil, trifoil, or quatrefoil when listing their accomplishments.
