New Garlean Event item

[Haibel]

So I did one of the new Garlean events, was outside of Ul'dah. I recieved a "Faded Page," and was wondering if anyone knew what it was used for?

Faded Page:

A slip of paper covered with arcane sumbols and queer handwriting. Used by imperial operatives to identify the handwritting of the Twelve Archons.

Also received 3 deaspected crystals.

An Elixir dropped from on of the mobs too.

It's a party invite to the Blue Oyster.
