i think you can buy them via the librarian in altdorf's library - not sure if you need somet other than money to purchase them though. They have different prerequisites to purchase

Ran around Altdorf yesterday, you can buy them with normal money, but it seems there are some requirements that needs to be met before you can buy them.
for instance you can get the first trophy for killing 1000 of a certain mob (for instance chaos spawn).
This will create a tome unlock entry and once you go to the librarian you can buy the trophy.
