Short version: There are 4 other planets in the system. 2 closer to the sun, both very hot, and a gas giant out past Hephaestus. This planet itself has 3 moons, two of which are basically oversized asteroids, one of which is a "proper" moon. There's nothing much else in the system in terms of human made stuff. There are a few sensors on the moon and scattered around on other planets, but mostly just basic monitoring stations so Hephaestus can keep an eye on the solar system.
Starting from Hep's jump point, there are dozens of systems that are reachable within reasonable time and that are inhabited, but in terms of using one of these systems as a staging base, only three or four. Two are simply large colonized worlds. They're not particularly special in terms of anything they make or their military, but they have established infrastructures and the capacity to be fortified and to work as staging points. The Third is a world near the jump point. It's tactically useful because you could use it to control the point, but there's nothing of any real interest in the immediate area, so no one has done that. The last is questionable. It's just a large asteroid field with a lot of abandoned infrastructure they could use. Not a whole lot out here to be honest. Heph is in the boondocks. Part of the reason we grabbed it.
