From publisher blurb:
Before the first orc drew breath, dark forces stalked the world of Argor. Even as the first of the Free Peoples explored their new lands, fell creatures, dread curses and dire plagues awaited them. Together, these abominations became known as The Bale.
This is a supplement to Argor FRPG that introduces the undead into Argor. There are full details on the seven Bale races:
To even things up a little, there is also a section on the Creed of Anamordeus, magic users dedicated to cleansing Argor of the undead, with nine new spells and three new magic items for use in your scenarios.
