Mrisst is a word of lush tropical jungles and warm, tempest tossed oceans. The single supercontinent that spans the globe boast a central spine of tall mountains running from the north-east to the south-west. There are a dozen mountains over eight thousand metres in height and over one hundred that are at least seven thousand metres at their peak. This central spine is bordered on both sides by thick jungle, with trees reaching over two hundred metres into the humid blue sky. Thousands of species of vines and epiphyte cling to the broad branches and sprout flowers in a myriad of colours. The air is thick with the sounds of insects, birds and reptiles calling to attract mates, mark boundaries and signal the location of food sources. Humidity under the all encompassing canopy is always near one hundred percent and explorers are advised to have cooling equipment to prevent them from losing too much sweat.

The planet’s one ocean, capping Mrisst’s northern hemisphere is perpetually storm tossed, with waves dozens of metres in height regularly pounding the continent’s seaside cliffs. Great behemoths inhabit the depths, regularly visiting the surface waters to feast on whales and shoals of fish, and posing a threat to any seagoing vessel smaller than thirty metres in length. Mrisst has a solar day of twenty two standard hours, making adapting to the planet’s circadian rhythm easy for may sentient species.

There are no large cities on Mrisst, save Mennaa, the capital and gateway to the planet. Mennaa, situated on the world’s southwestern coast and surrounded by thick jungles, hosts the only major starport and is the main entry and exit point for trade goods, especially Mrisst’s valued hardwoods and natural medicines. The native Mrissi safeguard their independence fiercely, not through force of arms, but through active and intelligent politicking and alliances with nearby systems. Originally a member of the Galactic Republic since being discovered by the Tenth Alderaanian Expedition during the era of the Old Republic, Mrisst is now an independent, self-governing world with active diplomatic ties with a number of governments in neighbouring sectors and numerous embassies and consulates scattered throughout the galaxy.
