Przemo_No: Thanks but nope. Got that area too. I'm currently doing the Seeker Droid chain.
Damned good suggestion though. Bravo (no sarcasm)!
Well, Indeed, it's not the one, sorry. But as far as I remember there is some H4 in that area, and definitely accessible by walk-in, however I guess you need to obtain that quest (or a chain) - I remember I was there, by my Shadow (quest) and Assassin (exploration)
