Welcome

As for old cultures and ruins, try Khem on Amia B. It has several ruins and an (hopefully soon again) active Mulan presence. Though, I wouldn't head out there as a level 3 or anything. It can be a bit scary

But the Eastern cultures would be something you'd probably like, like Mulhorand, Thay, Chessenta and Unther. The source book Old Empires might help you out.
