There was such a rumor on the official forum!
The first level of the Graveyard of the Gods was not really considered as part of the graveyard. It was merely designed as a sort of test. The kind of place where the weak would be prey for the strong. It was a screening layer as only the strong would survive.
Only the players who had passed and survived the trial could find the warp portal and advance to the second level. Those were deemed as the strong ones who could enter the Graveyard of the Gods...
However...
The area of second level of the Graveyard of the Gods was apparently much smaller than the first level.
Unlike the first level, the second level was no longer a single layer environment. The whole area split into different territories and the environment of each territory was extremely complicated.
