Seems like they're preparing a new part of Time Temple.

I was reading the quest log data and I'm not sure if this quest comes after defeating Cygnus, but basically Shinsoo has a quest for you and says "This is not the future" and to meet up with him in present time. Then, "You learned that the Gate to the Future actually leads to a dream world created by the Black Mage.
Return to the Black Mage's dream world and search for some clue as to the Black Mage's identity."
Shinsoo then says to defeat Cygnus again. You then find a Dream Fragment and talk to Athena (present time) about it, who has no clue about it and is acting strange. So you go to Neinheart in present time.
"You've learned that the Black Mage has a follower who can create and manipulate dreams. This Dream Fragment might be related, but...why was it in the future?"

And that's pretty much it ( I think)

You know, It's starting to amuse me how much Neinheart seems to just know about these guys. Athena I can understand, but.. dude...really? Now I am sad because my highest level is only 115 and I won't even be able to screencap these wonderful quest for quiet some time. :C
