Publisher's blurb: Castle Nimentar takes the players from Camp Highmore to Lake Luo deep within the Jungles of Chult on a quest to explore a haunted ruined castle out in the lake. They will be faced with beasts, constructs, and undead, and puzzles such as how to get to the island, a haunted theater, and a chess game. They'll be searching for treasure, especially a magical scroll known as the Nimentar Scroll.
