From the back cover:
The Wait is Over
After eight years in development Frog God Games finally brings The Slumbering Tsar Saga in its entirety: three books, 14 full adventure modules, more than 80 maps, and hundreds of encounters all compiled into one epic volume.
Travel from the dusty frontier streets of The Camp to the innermost workings of a demonic plot 10,000 years in the making. Witness the bleak expanse of the Desolation, roam the ruined streets and bastions of the Temple-City of Tsar, and plumb the depths of the vast Citadel of Orcus, lost from the knowledge of mankind for hundreds of years. Do the heroes of today dare tread where legends of the past failed?
The Truth Lies Within
The Slumbering Tsar Saga includes the three mega-adventure books: The Desolation, Temple-City of Orcus, and The Hidden Citadel combined into one continuous adventure path taking characters from 7th level all the way to 20th level and above. Each book includes hundreds of different encounters for thousands of hours of play as well as new magic items, monsters, and player handouts. Challenge your players with this adventure of epic proportions, but warn them to bring extra character sheets.
Only true heroes of legend will emerge victorious. Orcus takes the rest.
