As the Pathfinders lounge at the bar, Venture-Captain Heidmarch comes running out.
"... hurry!" she pants, out of breath. "You must ... hurry!"
Heidmarch shows the Pathfinders one of the papers that they recovered from the Bronze House. It's only an accounting ledger, but shows that Aspis agent #322 was given a down payment for the job of recovering a lantern for use in the Grand Convocation project.
"Based on the per diem pre-authorizations, we believe that the lantern is housed at the Blakros Museum in Absalom. You must return to Absalom with all haste and secure this lantern immediately - Kreighton Shane will meet you there with any details we uncover during your travels."
