the letter is written in rat blood on a broken piece of paper.
Caleb,
Lockwood has agreed to meet you in a neutral place to discuss about your 'contract-provider'.
I assume you did show up to the little 'party' waiting for you with 'me' stuck in that crap, and left when Bungo saw you.. or thought he saw you. doesnt matter, that was a 'front', you were going to charge for using necromancy, but the real deal was that Lockwood wanted to meet you. You have friends in common, and might be in grave danger. Listen, I dun care as long as you dont get me involved in your problems. He will be expecting an answer shortly.
-Maalgor.
