The Diamond Regiment is an Andoran army group consisting of about 388 regular army soldiers alongside 12 Eagle Knights. They are based out of the tower of Adamas. The primary function of the regiment is to ensure that shipments of Darkwood travel through the area safely on their way to the Andoran shipyards. The regiment is headed by Commander Ingrid Odeber, a paladin of Iomedae. Through her it has ties to the druids of the Greenfire Circle with which the regiment cooperates.
The insignia of the regiment is a gold patch with a black and grey silhouette of a falcon carrying a sword. At the bottom tip of the patch is a red (denoting sacrifice) diamond.
