Quest for the Quantum Rose Episode 3

After a quick shopping escapade in the port city of Sekand, in which our heroes completed the time loop from episode 2, met a Tabaxi weaponsmith named M'aiq T'aisson, and discovered a link between the pirates that had been harassing our heroes and the shadowy Elephant Graveyard Acquisitions, an antiquities and artifact trafficking organization. After being given a mission to investigate reports of a disturbance at a nearby archaeological dig, what will our heroes find waiting for them in the canyon catacombs of Idn Kar?
