The Obiah is a garment in Isaac Asimov's Foundation series.
Description[]
The Obiah is the sacred sash worn by Mycogenian men within the Sacratorium. A long, red sash worn over the left shoulder and tied at the right waist, the obiah is often intricately embroidered. It is a symbol of the joy a Mycogenian feels upon entering the sacred space and a representation of the blood they would be willing to shed in its defense. Wearing it is a sign of devotion and is required for participation in Sacratorium rituals.
