The Enmity Of My Enemy
An entry on gratitude missing from their dictionaries, the surviving sylphs have flown back to the Sylphlands to gather reinforcements...and launch an attack on you! Fend off the waves of budding beastmen while seeing that the lightly armed Mianne Thousandmalm stays in the realm of the living.

Its actually really easy as a bard, just make sure you have your aoes ready and maybe a chocobo friend to help.
Oops! This is embarrassing
We don't have much data for The Enmity Of My Enemy right now, if you have some to share please post a comment for others kupo!
@stinkpalm There are a couple of FATEs in the immediate area. It's possible that you're completing http://xivdb.com/fate/610/The-Enemy-of-My-Enemy / http://xivdb.com/fate/611/The-Enmity-of-My-Enemy, whereas this Beastman Quest needs http://xivdb.com/fate/691/A-Wrench-in-the-Works. If you have been doing the latter and not getting the http://xivdb.com/item/7002/Proto-Armor-Identification-Key in your inventory, the only thing I can think is either you're not getting a high enough rating or that your inventory is full (it appears in main inventory and not Key Items). Hope that helps!
