Then I take it you're very disturbed that prior to the dev meeting, Darkness owned 20 planets, or so, with most being hidden systems? >_>
Darkness currently owns 2 planets. One is the planet from above mentioned, which is actually capturable if I remember correctly, depending on who build what in the non-Darkness cities. The other, is an old hidden system planet that was kept around for other reasons.
I'd like to either sell the Trax one to the market at some point, or just let nature take its course and city decay, or the other city owners do their business.
