The Bishops of Gard are the regional leaders of the Faith of Gard. Each province surrounding Whitehelm has its own Bishop, answerable to the Arch Bishop in the capital.
A Bishop has many jobs beyond being a leader of the faith, including acting as a magistrate, and also as an advisor to local Lords and Nobles.

Unlike the Bishops, the High Paladins remain in the capital of Whitehelm, each one leading a company of knights, who can can ride out at a moment’s notice when aid is required.
The High Paladins, answer only to the King himself, but are otherwise quite autonomous, and will often deploy themselves either at their own whim, or the whim of the Arch Bishop.
