Ember comes from the Old English æmerge — the glowing remains of a fire that survive after the flame.
Ember entered the U.S. top 1000 in 2015 and has risen explosively. Today it sits in the U.S. top 175. The Pixar film Elemental (2023) features a heroine named Ember Lumen.
Ember reduces to three — the number of persistent quiet fire.
