I beat Mass Effect on the Xbox a few years ago, and now I'm replaying it on PC so I can carry my save over to ME2. I remember from my previous playthrough that I found a little station with a guy on it who sells really powerful, expensive, high-level items. I remember when I landed on the station, he was under attack, and once you kill the guys attacking him, he'll sell to you.
Unfortunately, I can't remember where this station is. I'm about to head to Ilos, and I can't remember if you can free-roam any more after that, so I'd like to find this station. Neither the station nor the merchant are mentioned on the ME wiki. Thanks for any help!
