From the back cover[edit]

For millennia humanity has traveled the stars, building empires that span hundreds of light-years. Those empires are home to a myriad of complex civilizations. This sourcebook takes an in-depth look at the cultures and societies of the powers of the BattleTech universe. Take a candid look at what life is like in the Inner Sphere, whether you're a Capellan who just gained citizenship or a Federated Suns student attempting to gain entrance to the prestigious New Avalon Institute of Science.

The Inner Sphere sourcebook provides information on the five great Houses—Kurita, Davion, Liao, Marik, Steiner—as well as the lesser powers of the Periphery. The Inner Sphere also offers general histories of each society, comprehensive maps and a section detailing ten key worlds of the Inner Sphere.



The cover of this publication was created in-universe in Means to an End. The characters are, from left to right, Rachel Barr, Chu-iKasawa Cho, Milton Rathburn, Diem Khamen Tvetska, and Lady Juliana Carsters. It was taken at the Second Whitting Conference by a man posing as Daniel Torrent, shortly before his death.
