I'm at level 20. I'm stuck on the level 15 story dungeon (Sastasha); haven't been able to successfully get in yet or got in with 1 other person and it was hopeless. Because of this, the story isn't progressing and so I'm not being naturally led to the next hub where I can unlock the level 20 leves.

So my question is, can anyone tell me where around Ul'dah I can find a levemete which will let me unlock level 20 leves.

One point of confusion I've run across when asking about this in chat is the following. people will say, sure I can see level 20 leves at NPC so and so. Well, thats only because they unlocked them elsewhere and so now can see them anywhere.

In other words, you have to find the "proper" level 20 levemete to unlock level 20s, then of course once you do that, you can access them from other levemetes.

I'm sure the story will naturally lead me to whatever hub contains the level 20 levemete unlocker, but while I'm stuck at the dungeon, can anyone point me there?
