Mosque is a snowy town north from the airport. The residents are disciples who have pledged themselves to a man called Beruga. Perhaps this is the same Beruga that Wong was talking of in Dragoon Castle. Beruga is known for his biotechnology theories and is now in a deep sleep in a cold storage unit in the laboratory to the south. The people in white cloaks say that Beruga will awaken one day from his laboratory in order to save the world.
There is a MagiRock in the northeast corner of Mosque. If you leave Mosque and walk to the east toward Siberia, you'll also find a cave where you can pick up the Black Rod.
When you enter Beruga's Lab the lights have been turned off. You will have to find the light switch in order to see. Walk east down the corridor. You'll also see a doorway that leads to an elevator, but the power apparently has been turned off somehow. Continue on to the east into the next area.
Head back to the entrance of the laboratory. The elevator now works. The switch to the left side takes the elevator up one floor, and the switch to the right side takes the elevator down one floor. Flip the right switch to ride the elevator down, and then get off at the next floor.
Once you have reappeared, head south and follow the hallway. You'll reach a room with four more transport modules.
Open the door to the north and enter the next room. The switch to activate the elevator is in the middle of the room. When you've flipped the switch, head to the east and then south to get back to the elevator. Board the elevator and get off at the next floor.
Walk up to the computer and turn it on. The database asks you for a password and of course you don't know it. Yomi pops out of the box and explains that this machine controls all the systems in this lab. Yomi suggests you use BLOODY MARY as the password, and sure enough that's the correct one for the database. By entering the password, the machine unlocks the elevator so it can continue to go down floors. The database also unlocks the cold storage facility that is on the next level down. The database also stores information as to what happened to the world. It records that the world's population was almost completely wiped out by a virus called Asmodeus, but Beruga had created a vaccine for it. Unfortunately there wasn't enough vaccine for everyone and so only a few survived. The database also talks about the hybernation chamber that Beruga perfected. Return back to the elevator.
Sometimes after defeating the robot, it will explode into about 6 smaller red microbots. The microbots aren't that difficult to destroy, just a little annoying. Once the security robot is destroyed, exit the room using the northern doorway. You'll come across a long chamber.
At the far end of this chamber is the all mighty Beruga himself. His cold freeze hybernation chamber unlocks and he wakes up. Beruga thanks you for awakening him, and says he's been asleep while he waited for the world to be resurrected. Beruga wants to show you what he has been working on, so follow him into another room.
He shows you a creature living in a large glass tube. The creature looks very similar to a zombified human! Beruga says these are humans that he has created and these "humans" are capable of living forever. Ark looks at the "human" and it looks back with a sad look in it's eyes. Ark asks if it is wise to revive the dead, so Beruga responds that only the unnecessary will die but the necessary will continue to live. That remark angers Ark and he tries to charge at Beruga, but some robots appear and immobilize Ark. Beruga explains that Ark cannot get close to him else his robots will kill him. He says that soon his "liege" will emerge from the underworld and he walks away, leaving his robots to finish off Ark.
The scene changes to the innocent NeoTokio, where people are doing their everyday things. Suddenly the sky is ablaze and people start fading away! Soon there is no one left alive in NeoTokio. Beruga is definitely a very terrifying person.
Ark then dreams of the Elder from Crysta. The Elder congratulates Ark on the excellent job he has done so far, but it is now up to Beruga to make the world a wonderful place. He says that now Ark's job of resurrecting the world is complete, and now Ark can rest for all eternity. The Elder fades away, and Ark realizes that he is about to die. He wonders if the entire time that he had been resurrecting the world, he was shaping it into what Beruga wanted. Suddenly a voice is heard telling Ark that he can not die yet. The voice explains that Ark has the ability to change this fate.
Ark awakes in a bed in Lhasa. MeiHou is standing over you. He is glad to see that you have finally woke up from your nap and how Lord Kumari arrived in Lhasa carrying your badly damaged body. He also mentions something called the Star Of Darkness and how it destroyed NeoTokio.
Go talk to Lord Kumari. He says that Beruga is the one that brought up the Star Of Darkness, and how humans can no longer die. Kumari says that to fix this problem, you must collect the Starstones and place them at the grave markers at time's end. He also explains that you exist outside of the normal loop of fate, so only you can find the Starstones and save the world.
