I've already found stories about Wyver and Olympia. Histories, would be more accurate.

[ Luckily, Cain's paying enough attention that while he does bump into Arjuna at the abrupt stop, it's only gently, and though his tower of book wobbles alarmingly, it doesn't come crashing down. A book does bump Arjuna's shoulder, though. Another the back of Arjuna's neck.

Not Arjuna's head, though — Cain would need to be a little taller for that. ]

So though the language may be poetic, I think it's safe to say that the information in these books is quite accurate. Which makes it very useful.

[ There's a note of triumphant satisfaction in his voice. ]
