It explains the immortals and their spheres of power, and covers Mystaran immortals, inactive multiverse immortals, missing immortals, and immortal candidates. Extensive appendices organize the material by sphere, name, hierarchy, interests, domains, alignment, ascension date, patrons, and player use. The volume is available in Italian and English.
