I played this at a 5-player table on Tier 3-4.
The scenario had so much potential--an opportunity to learn about the kasatha, solarians, the Idari, and Jadnura? Yes, please!--but it flopped at the end.
The tea house was fun, even playing a -2 Charisma penalty dwarf.
The temple was underwhelming. It seemed to simply serve as a sign post saying, 'Keep going that way.'
The lost ruin was interesting and eerie.
The boss battle was way too much and didn't fit the story that was billed nor the story that was being set up during the scenario.
Then when you get to Jadnura, the scenario ends with, "Thank you for rescuing me. I will return."
I would have better enjoyed the tea house as it was, a more fleshed out and pertinent temple encounter, the creepy ruined temple in outer space with its psychic traps, meet Jadnura, use the lessons learned at the tea house and temple to convince him that he needed to return to the Society, and then be attacked by a rogue faction within the Society that believes it would be better for the Society for Jadnura to never have returned and used the PCs to track him down.
EDIT: I did not explore the Idari as billed in the product description. I did not learn the history of Jadnura as billed in the product description.
