Cryovolcanic Moon
Actis, or Kepule I, is the first and smallest of Kepule's major moons. It is a geologically active, cryovolcanic moon. Geysers of volatile materials often erupt across its surface. Partially due to these geysers, it hosts a tenuous atmosphere of primarily nitrogen, with trace amounts of methane and carbon monoxide. Actis has a surface that is composed mainly of frozen nitrogen, a mantle of mostly water-ice, and a rocky core. The significant deposits of water-ice make up about 38% of the moon's mass. This, combined with its low surface gravity, have made it a valuable strategic asset for the fuel industry.
Actis get its name from the mythological character of the same name. The traits of the moon have no relation to elements of the myth.

Actis is commonly referred to as the second most strategically important location in the Kepule system (behind Tandua), thanks to its favorable conditions for hydrolox extraction. Its orbit being near the bottom of Kepule's gravity well means that potential-attackers will almost always be traveling "down" the well to intercept Actis.
While Tandua gets some of its rocket fuel from its oceans of liquid water, Actis is the primary supplier of hydrolox rocket fuel (hydrogen and oxygen) to the rest of the Kepule system. Water-ice is is extracted from the mantle, melted, and stored in pressurized tanks on the surface. Electrolysis is used to separate the hydrogen and oxygen, after which it is loaded into a tanker spacecraft that would transport the fuel to a destination, usually a space station, or sometimes a stranded spacecraft.
Utilizing both vertical and horizontal integration, as well as the occasional use of military force, the Indrine Fuel Company has maintained a monopoly on hydrolox rocket fuel since 4402. The Indrine Fuel Company was founded by Philip A. Indrine in 4380, with significant backing from the Tanduan government. It has long been argued whether the company controls the government or vice versa.
