"Captain's Log, Stardate 8054.1. We have received a distress call from Rikyu, an independent Saurian colony beyond the Federation border. Planetary governor T'Rimushei is requesting assistance with a natural disaster endangering the planet's cities, although she was vague on the specifics of the threat. The Saurians are famously self-reliant, so it could be that the governor was embarrassed to ask for help – but I got the impression that she didn't think we would believe her if she told us more."
