The Purple Factory

This lies in a valley a little west along the coast from Thuyakalrul. A purple dye, prized by the Chosen (especially the Wise), is extracted here from the bodies of ammonite shellfish. This industrial process uses a system of vats that scale the sides of the valley. Products and residues are flushed down through the vats by a river, diverted by means of sluices. Labour is supplied by sartlar. The resulting effluent running into the sea appears to be a river of blood.
