Jovia System is the setting for the evogame-style project, which focuses on the evolution of multicellular life. It is an F9V star with gas giant planets and their moons in orbit around it.
Life
Currently Cappu's moon, Iris, is the only multicellular life-bearing planet. Iris is remarkably Earth-like.
The bright faintly coffee-tinted gas giant Cappu is also life-bearing and although much evolution is taking place, most species currently survive by being extreme r-strategist single-celled organisms.
Just because species on Cappu are evolved doesn't mean that they're large or complex, on the contrary most lineages are branching off in a direction towards further simplicity, hardiness and efficiency. Iris on the other hand bears life of increasing complexity, size and levels of organization over time.
Satellites
All planets in this system are gas giants, with no rocky planets. There are however rocky planetoids and moons.
