Good Question! Remember that Giovanni Nandra is not an opposing force - he's more like neutral ground. Jack Du Vance (now Jezebel's territory) was also relatively unmanned, so its more like Orr's territory is the only thing holding them back from having a complete line down the east side of Nabius, with Tomacia at their back for defensive purposes. They could attack Marie Lafeye certainly, but the Orr estate is the more valuable property to go for first, as it links Alex with Ysabel I just realized I wrote Davora instead of Orr - thanks for the catch, editing that now.
