We rejoin the party after they have discovered and acquired the Barque of Orobias, a Spelljamming vessel created by the Duke of Hell, and attuned to through the sacrifice of Rhys to an uncertain reincarnation, which brought him back as a Tiefling. Although they are trapped in the re-sealed Halls of Orobias, the Barque will theoretically allow them to escape to the planes of the Nine Hells briefly, and then jam out and back to the Prime Material Plane of Fryth Anvor, free of the prison.
The Party Arrives, falling from the skies onto the beaches of Fryth Anvor, redirected there by a pair of New Faith deities.
