If the planets in their solar system are really that close as depicted, they would have massive gravitational issues. One (or more) of Jupiter's moons is volcanic because of the gravitational effects of Jupiter and it's other moons. While that picture "may not" depict the Earth like planet as close enough for it to be a moon, Earth's own moon is approximately the width of all other celestial bodies (other than the Sun itself) away from the Earth.
If that picture is anything other than a gross over exaggeration, the planet is not only far too close to be within the "Goldilocks" zone, but would also be pulled out of orbit by any of the other orbiting bodies, which would do the same to one another.
Lastly, regardless of whether it is a gross over exaggeration or not, a mass of fire, or heaven forbid plasma (as a solar flare consists of) THAT size would not only evaporate the atmosphere but also sublimate the ground. Everyone and everything would be dead, except for the Goddess who is incorporeal as a nonphysical being.
Seriously, the lack of realism in this "otherworldly" fantasy based-off-a-video-game fictional world just boggles my mind...
