The Tournament Theater (aka Knight Theatre) is a landmark in the Kingdom of Daventry that existed under the rein of Edward the Benevolent. It lay to the southeast of the Town of Daventry. It is the location where the Knights of Daventry have their Knight Audition and train to become the guardians of the kingdom.
It's unknown if it exists in later times.
Graham responded to a advert with the missive "Help Wanted. Only the bravest need apply! Meet at Knight Theatre for details."
This may have been the home of Daventry's Knight School.
A sign south of the town states that the Tournament Theater is to the 'west', but its actually located to the east.
