As the party begins to falter, a strange sight over the treetops calls their attention skyward. It is a sailing ship, some sixty feet bow to stern in the shape of a massive…fish? Not that they have ever seen a marlin, but they have seen the people who command her as they lean over the rail!
Teth and Ilithenlin have managed to resurrect an ancient Spelljammer taken by House Allevialir many centuries before, and uncovered its secrets. With their new transportation in control, and the undead army massing beneath them suddenly losing interest in them and running toward Waterdeep, the party realizes the Tablets of Fate must be nearing the Celestial Stair, the last place where mortals can touch the planes of the gods and return at last what was stolen.
Whoever returns the tablets, they reason, we have the favor of the gods. Envisioning a dark Seldarine pantheon, the party redoubles their efforts, only to discover the pulling call of the tablet directs them toward a small cave in a seemingly meaningless hillside.
Leaving guards aboard ship the party enters the cave, straight into the mouth of Hell itself.
