Strange Quest Rewards

Those of you that played WAR will remember the ton of grey items you could get via quests that were supposed to have a hidden purpose (but had none). While questing in the asmodian starter zone i encountered the Treasure of the Deceased quest, that grants you the Brooch of Ghost item as an additional reward. Does anyone know what to do with that or saw other grey quality rewards from quests yet? Maybe in Aion those items have a hidden purpose? When you use the "sell misc" button at a vendor, the brooch won't be added by default. You can sell it if you wish tho. Initially i thought there might be some connection with this ghost soldier running around the graveyard, since he did not seem to have any purpose either. I did not incquire further since i wanted to get my wings asap, but will have a look for it again come retail or open beta.
