At first, it seemed like that was it – interesting enough – but then they discovered a secret door, leading to a hallway, leading to a room with shelves full of books – linking books! No descriptive books, as it seems, but a big number of linking books. B.P. says, they counted at least 20 books of different ages.
Nobody knows, how Ri’tehraf was able to keep such a big number of books, when even the richest D’ni didn´t – the most likely theory is that he had stolen them.

Anyway – it will be difficult to research such a huge number of ages with a rather limited staff. Most of the expeditions members are already working on the ages we have access to yet, and so the new ones will have to wait for some time (although many of us can´t wait to visit them.)
