Jack stared vacantly at the pile of rags, dagger still drawn, while Bible and the dwarves talked. Then, shaking his head as if coming out of a dream (or nightmare), he looked up while smoothly sheathing his dagger.
"I have something," he growled while pulling off his pack. After a few moments of rummaging, he pulled out a carefully folded note and held it up to the party. "Found this, along with the dagger, among Azbar's stuff a while back. The Guild had trouble translating it. Said it was some kind of elvish script, but nothing they recognized. Best they could tell is it was instructions for that fiend to support the giant's efforts. As to why - and who sent it - they could not say."
