The generic loot list of bits swiped from Antigonus' castle mentions 3 scrolls. Praxos would keep them himself, but you have a general ide of what they area.
Document no. 1: This is some kind of family tree, in Lunar. Praxos examines it: he thinks it shows him and Antigonus and how they are related, but the generations before him have been rubbed out and redrawn several times. As written, it shows Antigonus has the prior claim.
Document no. 2: This is a fairly long (1000 word) document in some kind of cipher. It finishes with an official-looking seal: Praxos does not recognise it.

Document no. 3: The third scroll is a map. I assume Agvan would make a copy of this, because he always maps and he carries drawing materials round with him. See sketch map of Northmarch pinched off Antigonus, Fire 1621.
Mark: I assume Gelert has seen this and partially memorised it. He's hampered by being unable to read or write, but you should have a general idea what's on it. Just don't show this map to other PC's, describe what's on it if need be.
