I had a bizarre where I was in the final stages of writing a book and for some reason I was obsessed with fonts. I was like some secret agent trying to track down that elusive font that seems epically important. In the end I even broke into Microsoft headquarters and capped a few guards one my quest for the perfect font.
I thought it might be interesting to focus an adventure, or campaign maybe, around the idea of try to find a forgotten language. The idea would be that the group adventuring in some epic catacomb obtains a chest of books which they have no ability to identify.
When they return to a their wizard hookup he is unable to identify or read the text. If they try and use magic to read the language they find that it is for some reason unable to be read. The wizard concludes that during the last great war it was rumored a language was created that was itself magical. He tells the players that the language was used for spies and important messages that needed to be protected from even the eyes of a wizard.
The players are tasked with hunting down the decoding scrolls as their king desires to employ these lost magical encryption in his own endeavors. There are a couple ways you could go in having the players find the information:
- Intrigue and research: maybe the players do some research and find that the texts may be in an allied kingdoms protected libraries. The players would need to find a way to obtain the book without letting anyone know why, and make sure not to upset their kingdoms allies.
- The delve: If dungeons crawls are more up your players alley then this could be a great lead into a mega-dungeon of the fallen empire in order to hunt down the documents.
