Kojin (荒神) is a fire planet and the First planet in the Genbu System. Due to its proximity to its sun, Kojin experiences searing heat during the summer, and very hot winters. There is very little water on its surface, and is highly geologically active. Kojin is notable for its many lava lakes and powerful volcanoes. There is little vegetation on its surface, much of it dry. Kojin is the Japanese Kami of Fire and Heat.
Very few people settled Kojin, and those who did, scratch out a tough existence in some of the planet's more habitable areas. Maliki Hoburn was born on Kojin, his family were homesteaders originally from Benzaiten who moved to Kojin generations ago.
Little ancient alien artefacts have been found on the planet, and many believe it to have been overlooked by those who came before, due to it's hellish appearance. However, several monoliths have been discovered across the planet.
