The Order of Archivists, or Talekeepers, are very specialized spell casters generally self-learned they are to niche for the wealthy to fund formal organizations. Tale Keepers are generally from lower classes. 

Talekeepers are able to touch objects, places, and people and glean insight. They can channel the memory of the world to write histories though they can be difficult to understand for sapient creatures.  They channel their magic through the touch and acquiring information from it replaces other memories.  

Talekeepers are loosely organized but do not have a standardized ranking system.
