Aether Current Locations

[Terrini]

Nope, that's way off base, and no, you don't have to do any 59 quest to access the Aether currents in the Hinterlands. I had all of them collected at level 58. That one WAS touch to get at though because you have to go south quite a bit to the ramp up to that area and then come up around from the west, but it's definitely not as far out of the way as you are suggesting.
