Will we ever enter Aerial Cleft?

Well, chances are that it will take some time. At least at Teon.

Note added on May 9th, 2009: OK, cleft is finally open. Let's go!!

According to the patch notes :

"One can enter (aerial cleft) only when either the Seed of Destruction or Seed of Infinity is in a stable state".

If "stable state" means that the Keuceraus Alliance (that's us, the players!) should be occupying one of the Seeds, which it does, then I am afraid that a lot of coordination, power and expertise is required.

As Elmar said at EllieBelly.net

"Because at least one of the Seed strongholds must be taken for the Cleft to become accessible. In the Seed of Infinity you need a party of lower level players to do the first instance so that the 80+ people can get to the Epic Boss. That's unrealistic on Western servers; even in Korea it very rarely happens. So the only practical way would be to kill Tiat in the Seed of Destruction."

Now I think Tiat has been killed on Teon, however something has not yet been fulfilled since the cleft has not yet open.
