A well written piece that adds a few dashes of what what Mbala could have been in the distant past. Has reasonable plot hooks to get your players to Mbala. Offers several beautiful maps, one of Mbala and two battle maps. And offers new motivation for the resident's NPCs actions that are fully reasonable.
I like the addition of the mummy and secret tomb, and the Rain Stick is a very nice item that grants use of cantrips that are not over powered but will reward a creative player, and a +1 quarterstaff is not going to break the game. And the fun of an over eager player nearly dying to the mummy to receive this was great for the table
I am only part way through as of this review but I am really looking forward to the rest of Mbala
