From the back cover:
"Ersille's loyal subjects say that it was the Queen's death which drove King Ovar to the brink of madness, to reopen the slave pens, to order the mass executions, to persecute the good but misled people of the kingdom, and to ignore the fact that he was no longer a king but a beast!
Four stalwart characters are charged with assassinating King Ovar. They must penetrate TOWER CHAOS and at the right moment strike Ovar dead!
TOWER CHAOS includes several scenarios, some which expand upon Prisoners of the Maze and Dimensions of Flight. Included herein are trend-setting tower encounter systems and schedule matrices, plus a mystery complete with an ironic twist...
