Winter Eternal (5E)

From publisher blurb: Some treasures bring you riches, others happiness. And some bring you to the Lands of Lunacy. Such is the case with a peculiar snow globe. Inside the globe, snowflakes swirl around an icy tower on an island centered on a frozen lake. A short gaze brings repose, taking thoughts of hard adventuring away and conjuring memories of youthful innocence. Lingering gazes fall prey to the enchantment of the globe and the mystery within.
