Obtain a Pearl of the Darkness in the World of Darkness. In Heavensward (3.0), brand new sightseeing logs were introduced. He thanks you for providing an entertaining spectacle, and declares his intention to reward your efforts. However, Rammbroes realizes─with some prodding─how tiring your journey truly was. Even as Doga and Unei attempt to annul the emperor's dark covenant, an entity calling itself the Cloud of Darkness pulls them into the rift that had manifested before the throne. Rammbroes explains that four varieties of an extremely rare abrasive known as aethersand are required to polish the flawless crystals. In the moments before opening the rift, G'raha Tia falls into a strange mood, and tells you of a band of heroes in ancient Allag who sought to dethrone Xande. The pearl forms over the process of a few years and only rarely does it naturally produce a spherical form. Most pearls were originally from the Far East (China & Japan). Rammbroes and Cid are saddened at the loss of Unei and Doga, but they are both happy to learn that your venture into the World of Darkness was a success. Participate in the FATE “He's a Firestarter” in Zahar'ak to obtain a flawless fire crystal. the two clones then tell the historian he can control the Crystal Tower, and bid you all hasten back to Eorzea. by some strange coincidence, it appears that the Roegadyn engineer is also intent on purchasing what little aethersand there is to be had.
Cid arrives to inform you the preparations are nearly complete, and bids you speak with Wedge at the Eight Sentinels. Take the purse given to you by the dig supervisor and deliver it to Serendipity, the master of the Goldsmiths' Guild in Ul'dah.
