As long as Ai might have a chance to get it too, I don't see a problem. Grats on a lucky find!
That reminds me...
I did some AI wars just for fun the other day, didn't pay much attention to it tho. AI players against each other were quite slow, lazy and not eager to fight until all of a sudden a world war bursted.
At some time, must have been turn 100 or so, I saw Gilden roam around with an Ashwake Dragon. I don't know where they got it, is Markin a badass quester? Be that as it may, at that moment the winner of those AI wars was decided.
I've had Fell and Strom Dragons, never an Ashwake, which you prolly can get through a pretty hard quest.
