The Heart of Glass (d20)
An adventure companion set in the Sea Towns of Ihlsa, where thieves, assassins, and undead forces struggle for control of the polluted coastal settlements. Characters of levels 2–3 investigate the plans of an undead lord and seek the artifact known as the Heart of Glass. The book details the Sea Towns as a ready-to-play fantasy setting, with histories, notable characters, forty-one encounter areas, and a double-sided regional map. It also introduces the Crna Ruk prestige class, the Hlobane orc ancestry, new monsters, spells, and magic items, including the Soul Thief, Blood Runes, and Heart of Glass.
