This Plugin allows user to use an written book on a named nitwit (green "useless" villagers with name tag) to set his story. The Villager than will tell his story to any player interacting (right click) the Villager. The villager will tell one page of the book per click and there is an internal cool down of 20 ticks (~1s) between the interactions, to avoid spam.
Just copy paste the jar file. No configuration, no permissions needed. Really simple Plugin with just a few lines of code, but a nice feature imo.
