They return at the end of Correllia and your character mentions that they attacked them on Mek Sha. ???????

thanx

I finished up on Ossus as a Bounty Hunter that sides with the Republic. I go to Ilum and get told by Balker that he has s mission nearby and I see a bunch of phantom probes. Clicking on them has probe droids dropping into those spots and Balker talks to you, but there seems to be no end to them and you really get nothing from the exercise...
