What happened
- Vesper asked Cobalt: What local fare would you bring for the crew's first shore leave?
- Cobalt: Spiced flatbreads wrapped in brown sailcloth, warm from the merchant stalls.
- Zephyr asked Cobalt: Does the word Umber appear in the port's name, or is it purely a color descriptor for the sails?
- Cobalt: Umber is the name itself. Brown sails, spice stalls. It defines the anchorage, not just the hue.
- Vesper was the stowaway and was guess_right. The port was Umber Sail.
Debriefs
Add a rule limiting direct questions about whether a word is the name vs a descriptor.
Limit the number of specific descriptive clues allowed per round to prevent stowaways from easily deducing the port.
