An Adventagonistic Christmas

You are one year into your 100 year transition into a mysterious celestial beast. You are six months into a midnight-black romance with Mr. Pages, a dread and nefarious member of that same race. The holidays are fast approaching, but gift-giving is illegal in Pages' culture. Stealthily determine the best gift for your wretch of a paramour, and leave it utterly defeated by your superior show of humility, goodwill, and selfless affection. You are going to get SUCH a good grade in romance.
