Stealing from Thieves

Nexus Prince Haramad has ordered us to not begin work inside of Oshu'gun as it might anger a certain powerful naaru. Sort of puts a damper on our operation. I think I might've found a loophole, however. You see, we're not the only ethereals drawn to this colossal diamond. A thief called Gava'xi has led a band of rogue ethereals into Oshu'gun and they've begun to dislodge large fragments from it. Your job, <race>, is to go there and retrieve what is rightfully ours.
