무풍지대

Can be found in Simulated Universe 2 and Stagnant Shadow for wind ascension materials. Natasha and March 7 can cleanse wind shear.

The term "doldrums" (also known as the intertropical convergence zone or the equatorial calms) referred specifically to a region near the equator known for its calm, windless seas, which caused delays and frustration for sailors. This literal meaning has extended metaphorically to describe a state of feeling stuck or in a lull, much like a Strormbringer failing to use their wind attack due to the lack of wind [shear].
