You walk into the room and it is like stepping into the grand library. Wall to wall and floor to ceiling is taken up by leather bound loaded bookshelves. All of the tomes are in varying states of decay and none of which are new.
A world where, instead of aging in years, the people age in knowledge. So, instead of dying once a general age was reached, they die once they achieve a certain amount of knowledge. A man could live forever if he never learned anything, or could die after reading a few choice books. Of course, the knowledge of the land would be regulated, like medical drugs.
