From the campaign:
THE LOST TOMES - Volume 1 - 16 adventures based on a secret society known as THE LOST TOME SOCIETY. This society is made up of 16 of the very best NPCs the players might ever come across. Experts in their chosen fields, and all of them have some form of a tarnished history and back story. The 16 founding members of The Lost Tome Society are making amends for their misdeeds by hunting down the greatest and most powerful relics, artifacts, magic items and pieces of lost lore while destroying evil along the way. PCs are tasked to on adventures of 16
very diverse types, genres, as well as a different look, tone and feel kind of variety.
