Fraa Erasmas with a standard wrap of the bolt.

The primary clothing of an avout, a length of newmatter fabric. A bolt, a chord and a sphere are the only personal possessions of an avout. Bolts are typically wrapped and folded, with the aid of a chord, to form a variety of robe-like garments. The thickness of a bolt can be adjusted to suit the weather. The color of bolts is sometimes ambiguous, though the bolts of the ringing vale avout are explicitly described as black at one point.


Fraa Lio wears a more revealing wrap when in combat.

Unlike a sphere, a bolt cannot stop projectiles, as the fabric will rip under pressure and needs to be sewn back together.

It is curious to note as the Chord, the Bolt and the Sphere could be considerd as references to a 1D (the Chord, intended as a Line), a 2D (the Bolt, intended as a Plane) and a 0/3D object (the Sphere]], intended both as Point and as a Solid).
