The first time Edwin went to L-02 was a long time ago, when they were first recruited to become members of Candrasa's crew. However, they took the path that had been made by the Candrasas. This time, the Himalayas took a path that was farther than before, not via shortcuts anymore.
It was the first time Edwin saw the L-02 in its entirety. This area is in the second lowest layer of soil but is filled with black oceans. The sun wasn't there at all, so if they weren't at a power level enough to be able to see in the dark, then they wouldn't be able to see anything in there.
The black ocean has a giant crystal bridge that is so similar in color to that still water. There are no strong winds there, hardly any waves at all, and it's just a very calm sea.
Himalaya took Edwin to the end of L-03, which turned out to be a black ocean. They had to walk down the crystal-clear path that descended before the road became flat again, and they were in the calm black waters.
