Codex Crusade

Embark, if you dare, on a quest through the twisted labyrinth of academia, where libraries devour knowledge, student morph into eldritch abominations, and librarians hide secrets that blur the line between genius and stupidity. 

If you read Borges once in a caffeine-induced fugue and have never recovered from the revelation that you might be an idiot, then this is the text adventure for you.
