Lords of Fluviallis
Once the home of a great civilization who were great patrons of the arts, knowledge, and mystic lore; but then a great cyclops necromancer came, Seroiko the Mind Lord, who conducted bizarre and mad experiments with the undead using negative energy. They drove him off the planet, but Seroiko found a craft that traveled between the stars – a sentient satellite disguised as an asteroid. Seroiko mind-jarred himself into the asteroid and then used it to experiment on the population of the planet, and after 100 years or so everything was dead. Now the planet is rife with undead creatures, including vampires.
The sun of this planet is called Endymion
