Phoenix rising quest

[JustPlainMomo]

What happens if I have caught the Phoenix before the end..? I don't even really know how I did it, but I somehow was able to catch it in the middle of my adventure through the cave. But I have it in my inventory and now I'm at the end of the quest and can't complete it because it's in my bag. Ive tryed to leave theough the exit ans it says that I'm "leaving quest area". someone send help.
