What It Does
The line's signature — the wind, drawn and let go where the hand says, and the carrying is the whole argument, and the one who cast it is the one who gave the blood. It is the air school's answer to the fire school's cinder tongue: the wind does not burn, the wind decides, and the decision is the one the ground has to stand in.
The Cost
Circle 5 · Air · Exchange: blood — casting time three rounds. On the ladder in The Veil, the blood rung is the price, and the meter pays the budget while the exchange pays the spell.
The Failure
The verdict is let go shaped, and the shape is not the one the hand sent — the wind is the one who decides, and the one who is decided is the one the story is about.
In Stories
The archmage's air spell; the one the camp does not cast twice, because the sky remembers.
The door's scale anchor is Galeforce — the dragon casts it without thinking, which is how a reader learns the shape of the thing.
