Clothing

Clothing manufacturing varies widely by region, though the interconnected nature of trade in the Eastern World has begun to homogenise the methods used.
Within the Sura Empire the fibre of Npago plant are spun into fabric; the consists of the pappus, a fibrous ball that forms within the seed head and unfolds into a parachute-like structure after the flower dies off. The fibre is extremely lightweight, breathable and flexible, allowing for clothing accommodating to the climate of equatorial Sura. The gold thread of the Intessa is used for highlight gilding on clothing.
The Dellaci plant of Pascent is widely used there and one of the largest crops in Juventius. The Dellaci is a thick stemmed grass; the outer shell is peeled off and the bast fibres inside the shaft are baled and a controlled burst of electricity (usually supplied magically) is used to break down the connections between fibres. They are then washed and spun into yarn and then fabric. Dellaci fibre is stronger and lighter than Npago fabric, and so it is progressively gaining traction against its dominance.
On Victellus and Lissimo, the fur of the Osa Ellu is widely used for warmth, though sometimes it is spun mixed with Npago yarn to create a lighter fabric. The people of Debenya widely use the wool of the Gwek or the fibre of the Aso Aso - which is a large succulent plant, whose leaves are dried and then divided into small fibrous strips and woven into clothing. Manufacturing is not industrialised on Debenya however.
Morioka and Liang make use of various related species of large insect, whose soft webs are collected and spun into fabric with a highly prized softness, strength and opalescence, but which is largely resistant to attempts to dye it. This fabric is known as Rikku. For the less wealthy, fabric is spun from the fur of the Osa Ellu - imported from Victellus. Before the Osa Ellu, the use of the wool of the Wafoshi was common, but the wool crop was smaller and the species less hardy, leading to their phasing out about two centuries prior.
The trading kingdoms of Tulan largely import Dellaci fabric from Pascent, or Rikku for the wealthiest.

Dye

The most prestigious dye in the world is Vis Blue, made by grinding Vis crystals, which produce a vibrant and permanent cerulean blue, which additionally allows for magic storage in garments.
