You have to do the quest 2 or 3 (I'm not 100% sure, I have weird memory) times for 100 percent clear. First you have Ultor move all the way to the area labeled Metro. Quest completed first time. Second time you move to move him all the way to the forum. At this point I believe Zedus is unlocked. Move him to the palace then the Boulevard to get the chest. Then move him to the Forum with Ultor. Here you fight Draegar and once he is at 50% he flees and you unlock the last area, Pantheon. You are given the option to rearrange your squad members. Organize the squad with Ultor AND Zedus to be able to beat Phaeton. I used 7* Tridon, Elimo, and Nemethgear. Once you are done reorganizing, move the ZEDUS squad to Pantheon. Phaeton does not hurt that much other than a few large attacks which it warns you about. Phaeton will take a lot of damage so be patient. Once you beat Phaeton with Zedus you get all the rewards for 100% clear and you just need 2 Void Chunks to make both spheres.
