The Faxons really were a quite charming people and were the other principal civilisation on the planet Zizzdum. They had a sense of smell that was many times more sensitive than domestic dogs on Earth. They had little else in common with dogs, however, walking on 2 legs as well as liking cats, keeping them as pets once the first Earth settlers introduced felines to Zizzdum.
The Faxon sense of smell was so great that they could detect rare minerals and elements in very small quantities. As a consequence, they could command significant salaries working for Earth-based mining companies. Whilst Faxons could speak to each other, and to humans, they often preferred to communicate silently among themselves through releasing odours from their com-gland, situated just behind their ears.
This method of communication, whilst very effective, could become very confusing at dinner parties where humans might unintentionally be releasing their own ‘gaseous’ signals. There was many an embarrassing moment at early official banquets on Zizzdum when Earth ambassadors inadvertently said something rude or on occasion, made a pass at a female Faxon through natural bodily functions that had been activated by the excellent though wind inducing Faxon cuisine.
