Heart of Shadow
This sourcebook explores the Northern Marches, a frozen and corrupted region ruled by the dark god Izrador. It details the orcs who were born and trained there, along with the twisted creatures, undead legates, ancient crones, and warped magic shaped by the Shadow’s influence. It provides material for adventures and campaigns, including new prestige classes, creatures, creature templates, NPCs, and rules for the corruption of soul and spirit. The book also reveals the grave of Izrador and expands the setting beyond the northern edge of the map.
