Hey, kids.
I ran my first session a few days ago, and it went very well. We'll play again in about two weeks.
Some notes--each player had to explain a debt they owed to the Witch Queen of Yith. Then, as payment for that debt, they were asked/told to escort a small caravan from Yithorium to Xambaala. We began just outside the port city, having travelled for a good week across the sands. Part of the hook is that when they looked into the crates and sacks they were transporting to Xambaala, they found an assortment of slaver's tools--manacles, neck restraints, etc.
They took a detour to explore an island--I used the Stygian Library to create some weirdness in a tower. Soon enough, though, I think they'll head back to face the troubles of Xambaala.
I really did the adventure layout and contents--easy to navigate, but full of ideas.
Thanks to all who offered advice!
