Travelbooks

Travelbooks exist in pairs of two, they have a link so that what is written in one can be viewed in the other. Most of these books where used by scholars, sending out people to gather information where some where used by Adventurers that explored the most dangerous parts in the world writing down their findings, having a copy of their book safely stored in a library or other such place.

Access & Availability

This is 2nd age technology and the knowledge of how to make one has been lost so the only travelbooks that still exist are onse that survived throughout time.

Complexity

They are difficult to create but once created, they can be used by anyone (provided that the creator didn't specify a usability lock).
