Dust

A spark of green faelight flitted through the nursery window as the last rays of day faded from the sky. At its a center a faerie, no bigger than a single mote of dust. It flew around the room once, twice, three times, before finally settling on the edge of the cradle.

"Took your time getting here," sighed a voice light as the wind.

The faerie shook its head, regarding the human infant below sleeping below. "I came when I could, Woost. The child isn't in any actual danger."

"Yet," Woost replied. "It's only a matter of time."

"Perhaps," the faerie said. "These things are never entirely certain." It paused a moment, contemplative. "Still, best be on with it."

With that the spark lifted off from the cradle's edge and flitted around the infant's head. There was a tiny, infinitesimal sneeze, and a fine mist of dust drifted from the fae light and settled onto the infant's face. Tiny glyphs formed along her brow, just slightly darker than her skin.

"There," said the faerie. "That should be enough. For now."
