Cracklenight

The term cracklenight refers to a weather phenomenon found in the northern reaches of Avistan. Temperatures can suddenly drop overnight in the early parts of winter. The next morning residents find the ground, trees, and their homes covered in a thin layer of brittle ice. As most fall crops do not survive many of these freezes, farmers often use the first cracklenight as a signal to bring in the last of the season's harvest.
