i'm stuck too. i've talked with everyone (or been told nothing to see here) or have been shot at, have gotten a few coords for an artifact or two but i am now a little lost. I'll take some spoilers if you don't mind!

heh. Nice tip. Good old Wikipedia.
O class is BLUE! Only a handful of them out there. Finished the quest off no prob.

The mission is pretty vague... Orbit all planets on "Type O" stars in "this region" of space. Hovering over the stars do not show the TYPE of star. What is a type O star and how can i identify it? Otherwise i guess i'll just fly around and orbit every planet around Myrrdan until it says complete..
