Just to confirm, found someone else with 2 cubes today and we unlocked the datacron between us. I've made the relic on the republic side, so it definitely works.

Thanks

Can anyone confirm the green shard is actually obtainable with the 4 cubes? I've done some google-fu and some beta sources were claiming it was bugged, and didn't give up the shard correctly. Don't really want to go to the trouble of scouring the planet for these things for nothing. Found one at -161, -2012
