Tymerian Empire

The Tymerian Empire was the empire of the Tymerian race, ruled by her Royal Tectrope. The fall of the empire was a direct result of the outlawing of doors, after her Royal Tectrope got her fourth proboscis jammed in a suction door.

As a result, members of the empire had to use the stairs instead of lifts and windows instead of doors. Productivity dropped and the economy eventually crashed. (TDA: Forever Autumn)
