Okay, actually this isn't MY Faded Heart. One of my friends just completed the quest and found the heart so disturbing she just wanted to get rid of it. She wanted nothing in return, but in my view it's an odd sort of rare object. Usually I'd just add it to my collection, but it feels weird to do that this time. I don't think my friend understands that this item has value. So I'd like to sell it and then offer her the money. She doesn't know I'm doing this, so if it turns out no one wants it, that's okay, too.
NOTE: Since handling the Faded Heart before completing the quest will screw up the quest, I'm only willing to sell this to someone who has already completed the quest or who already has another Faded Heart in her or his possession.
Please leave offers here. Thanks!
