[Spoilers beyond...] Intergrated this into a Ghosts of Saltmarsh campaign. Works well before or after Isle of the Abbey but before the Final Enemy. Used it to give the PCs some much needed XP and to start ramping up the Sahuagin threat. The homebrew Eel Folk found in this adventure can be pretty much swapped one-for-one for Sahuagin. Although it's about the length of a typical one shot or Adventurer's League module there are several interesting NPCs here with opportunities for social interaction/conflict.

The author is known for a light weight yet effective presentation style that makes prep easy and quick and it mostly works here. The adventure is lacking a map of the island to tie everything together and help the DM visualize the situation fully and there may be a couple of errors (like a 10' ladder that can be used to climb down from the roof of a 40' high chamber).
