Eloon was the young Shayla's home world. Home, incidentally, to a hundred million other people, but for the most part that didn't register on an eleven-year-old's mind.
The planet belonged to the Family Firenzi, and lies close to the border between Firenzi and Imperial Skamensis space.
Some of the old Eloon's good points: Far enough removed from either territory's capital, or any military or industrial center, to enjoy relative peace and freedom. The planet was quietly prosperous, but not enough to attract unwelcome jealousy. Successive planetary governments worked to keep it that way, keeping a low profile and building an oasis in a troubled galaxy.
The problem? Shayla's father, on the run from the wrath of his mother, the tyrant Empress Florence, and from his brother Ivan, chose to live in hiding there.
If he'd been content just to hide, he and Shayla would probably have lived peaceful lives. As it is, he continued working against the excesses of Florence's rule and built a substantial network on Eloon. When Ivan finally tracked him down to Eloon, his organization was so entrenched that no amount of covert action could root them out.
Ivan, acting in the name of his young nephew (the newly-crowned Emperor, successor to the late Florence) had some large battleships to play with. And wholesale planetary destruction was a well-practiced maneuver.
