I've now run this adventure for two separate groups, and both seemed to go down well.
I particularly appreciate:
- The adventure effortlessly works as a miniature sandbox contained within the confines of the islands - I don't feel that the adventure railroads the party as much as one might expect for a one-shot. The constraints seem natural.
- There are often multiple solutions present with DC checks to solve problems.
- The timeline leading up to the adventure and the background outlined - this gives me (as a DM) good knowledge to fall back on when players ask questions about what they see can infer.
- The clues sprinkled through exploration, the players really seemed to enjoy the flavour text they provided.
Both sessions ran the essential parts of the adventure, taking about 5 hours 30 minutes each, both skipping over an optional part of the adventure.
