Beyond the scope of the mundane world lie the infinite planes: realms of
gods and demons - and treasures beyond imagining! Four veteran game
designers from the classic Planescape setting - Monte Cook, Wolfgang Baur,
Colin McComb, and Ray Vallese - have reunited to write this collection of
18 modular new planar locales. Included in this d20 sourcebook are full
details and descriptions of each region, plus dozens of new monsters,
NPCs, magic items, and spells unique to these planes.
