Knights of the Eclipse

Drakonheim: City of Bones Preview 2

From the introduction:

Despite all the efforts of the Gray Society, many in Drakonheim do not trust them. For too long necromancy and the undead have been a source of terror and the province of dark gods and demon lords. Most who feel this way simply avoid the Gray Society as they feel powerless to stop it.

The Knights of the Eclipse, however, are fighting back. Despite what the lord mayor and the city watch say, the abominations are evil and must be destroyed. The Knights of the Eclipse wage a crusade that started by attacking the skeletons and zombies that roam the streets at night. Twice now they have also killed minor members of the Gray Society.
