Iasci

The Iasci are an aquatic species that originate from the planet Iasc which lies within the Carina-Sagittarius Arm of the galaxy. Iasc is a wetland planet, where large pools, lakes and rivers are surrounded by dense forests, and large areas of the planet are covered in a light mist.

Iasci are able to survive for a limited time out of the climate of their home world but if they are away from the dampness for too long, their scales begin to dry out and they have difficulty breathing. To enable prolonged interaction with the galactic community, the Iasci wear ‘wet’ suits to keep their bodies moist, and they wear water collars around their necks and gills. The collars constantly filter the water via a small pump, removing carbon dioxide and continually replenishing the dissolved oxygen content. The suits and collars are not worn at home, where the atmosphere is kept as damp as their wetland home world, and where there is a swimming pool or waterbed within diving distance. Visitors to an Iasci household will tend to wear more water-resistant clothing, and an Iasci host will always have a supply of mini-rebreathers on hand should the guest find breathing difficult in the damp atmosphere.
