True Lovers Run Into Strange Capers (5E)

From publisher blurb: A 5th Edition Mini-Dungeon adventure for 4-6 PCs of levels 14-15 Eternity at the beck-and-call of an immortal outsider can become...”mundane”...while existing simply to extinguish other creatures’ lives eventually turns out to be equally tedious. But surprises rouse even the greatest of outerplanar beings from their ennui. And love is invariably a surprise.
