Lingering Love

If a non-evil humanoid creature spends a day
within 30ft of the star, they become target of its
magic. Whenever such creature would die within
30ft of the star, they instead get the benefits of a
long rest and the star gets destroyed.
The magic in the star is so faint that only a 5th
level spellcaster can discern its true nature.

it a safer place"—Ice-T
