Ember Snow -

Elara watched the girl’s ash-stained nightgown turn white. And for the first time in forty years, she told the truth.

Ember Snow is a type of snowflake that contains tiny, glowing particles known as "ice nucleants." These particles are extremely rare and are formed when supercooled water droplets in clouds freeze into ice crystals. As these ice crystals are carried upwards by rising air currents, they are subjected to intense pressure and temperature fluctuations, causing them to deform and become distorted. This process allows the ice crystals to absorb and retain the energy from the surrounding air, resulting in the formation of glowing snowflakes. ember snow

It was real snow. White. Cold. Silent. It melted on Elara’s cheek like a kiss from a ghost. Elara watched the girl’s ash-stained nightgown turn white

They walked for two hours. Elara used her cane to tap the walls—not the official signal, but a different rhythm. One that knockers used in the deeper hours, when the Arc flickered and the snow fell sideways. A rhythm that meant follow me, I am not leading you to safety, but I am leading you away from here. As these ice crystals are carried upwards by

While these theories provide some insight into the formation of Ember Snow, much about this phenomenon remains mysterious and unexplained. Further research is needed to fully comprehend the underlying physics and chemistry that give rise to this rare and enchanting phenomenon.
