[Nico scowls, though it's not directed at Stefen.]

Most popular theory we can come up with is that the Drabkeeper's Castle had information someone didn't want us to find, and they didn't care much about the people that had been inside. We just have no idea who that might have been. It's easy to point the finger at the Unseelie, but there's the possibility that a third party had a hand in it, which I'm hoping isn't the case.
