Spoiler:
A group of brave adventurers managed to uncover a fragile, smeared, and unintelligible map ripped at the edge and two things are only certain.
It's located in Impitur and it's close around the Vlasta region, any further deciphering would require some time and someone learned with maps and geography. Will this mystery ever get closure? It remains to be seen, as it lies in the hands of a few.
((A suggested route is the following:
Find someone that can decipher the map, you'll need to find a player with at least seven ranks in knowledge (geography) and need at least one day to decipher it successfully. There are other ways to handle this if you can imagine it, of course. Good luck!))
