There are five rivers that lead to Hades. Lethe, Acheron, Phlegethon, Cocytus and Styx.
Best known, the river Styx is the principal river of Hades, circling the Underworld seven times thus separating it from the land of the living. The Styx flowed out of Oceanus, the great river of the world. In Greek, the word Styx means to hate or abhor, and it was named after the nymph of the river, a daughter of the Titans Oceanus and Tethys. She was said to live at the entrance of Hades, in a "lofty grotto supported by silver columns."
The waters of the Styx is where Achilles was dipped by his mother Thetis, endeavouring to make him immortal; she famously forgot one of his heels. Cerberus, a monstrous dog with multiple heads and the tail of a serpent, waits on the further side of the Styx where Charon lands with the shades of the departed.
Styx Outpost stands sentinel at the mouth of the Hades Cluster within the Briar Patch in a lone Star system with Four Planets, each one named after one such River. What secrets does this area hold, what dangers does it contain and can Captain Keiben Haistro and his crew keep it safe from the Cartels, the Romulans and any others who seek to cause harm to the Federation.
