Right Click the shard and you get this in yellow text "The shard quivers and you get the impression this item is part of a set of three. Gather the other 2 shards to see if there is any reaction"

Falco Is God is on the right track (great name by the way) -- i just had a GM drop in on me in the game for another matter, and i asked him about the shard. He said it is for a special mercenary, once we find the other two pieces. But he didn't know WHERE to look for the other pieces, though....

Well it has a little picture that says 2/3 on the loot card for Claw of the Fallen Dragon, and in that picture is what looks like an armored merc or illusion or pet / familiar that you probably can get once u have all 3 of these.
Has anyone figured out what this is for yet, i got two of them in a wrapped ornament claim but can't seem to find any info on what they are for except for the three pieces part.
