I've been leveling my Imperial Agent as Light the whole game, and hit Light V shortly before finishing Corellia. After I finished the Act 3 story I went to Section X on Belsavis and got HK-51 as a companion. I'd like to increase my affection with him while questing on Makeb, but apparently most Light choices make him lose about affection while Dark choices tend to gain about 100 affection. I'm willing to lose Light V to get affection with him, but I'd like to have gear in my relic slots too.
What level 50+ relics are available that don't require you to be as Light/Dark as possible, and where can I acquire them?
