What am I?
Ipsen's castle, it does not look like any of the other towns and "My partner is gone - he's moved on for good" might be related to one of the Ipsen's plays.
In that castle you also get some information about the Earth, Fire, Water and Wind shrines (or caverns, I can't remember correctly), but you didn't learn about the guardians and traps, so that might mean "an incomplete archive of lore".
I hope that's not the answer. Not saying you couldn't make it fit, but it would make the riddle itself a terrible riddle.
