Selling a dragon with art/lore, trying something a little different:
A bitter dryad doomed to slowly wither away from the toxic wastes that polluted their home. They are the sole remnant of a once lush forest, a haven for their kin. Now all that remains is a poisoned land, barren and unsurvivable. They too, will one day rot away like their fellows. But before that day comes, there is something that they must do. They desperately search for something before their time is up, but what? What is it?
