Yep, it's that big tree between the churches. But I got another problem here... I've started this quest with a blacksmith and To find that trinklet it seams I have to collect from a flower. Since it's not a wildflower and I'm a blacksmith I can't seem to be able to collect it. Weird :/
Strangely enough, after wandering around the field for hours (game-time, of course) I suddenly started getting the option to search for trinket when I clicked on things that were collectible. Not obvious and extremely frustrating because this option was definitely NOT appearing earlier. I wandered around cllicking on things forever, it seemed before the option began to show up.
