Having the characters and the last thing they remember, the open scene is:
Each character comes to instantaneous, complete consciousness, and finds themself dressed in loose clothing of fine cloth at a table piled high with food of all varieties. Across from them, against the wall is all of their gear in neat piles and a tall woman with black hair, that flashes gold in the light and golden eyes with diamond shaped pupils. She introduces herself as Mariassa Sorrow, Satrap of the Gate City of Caracossa and invites them to partake of the feast, construct servants serve them all (except the elf is not given wine and must be content with water).
After dinner there is some questioning, Sorrow explains that the characters are better off here than they would have been had her people not picked them up and in exchange, she expects them to use their talents for her. In return, they will be equipped and rewarded. But, they must also agree to act as her agent and wear their choice of a necklace or bracelet of polished black stone, which flashed with her mark as it was donned, which would allow her to locate them as needed. Sorrow is seeking the location of the Eighth Gate, for only seven of the eight gates have been discovered, and the prize for finding the Eighth, well, it would be astronomical.
