Anyone know what this is used for? It is numbered FRN0931.

Once you fill the order, give it to Merchant Grekin (796.79, -25.62, 329.37) in Starcrest Commune. Most of the orders can be filled in The Forest Ruins off of Baubbleshire.

Here's an interesting development...I have one of these quests, which says to kill 5 fawns....I went to the appropriate area, found some fawns which were green to me. I immediately began whacking on this critter, but was unable to do any damage to it; plus after the first two swings, I began getting a message that I would no longer get credit for this encounter. Anyone else run into this? What am I doing wrong?
