The Synod is one of the organizations formed after the dissolution of the Mages Guild at the start of the Fourth Era, the other being the College of Whispers. The two groups are rivals, and constantly strive to earn the favor of the Elder Council. The Synod played a part in defending the Imperial City from Umbriel circa 4E 40.
The Synod is headed by a Grand Council. Ranks within the Synod include Attendant and First Adjunct. One of the divisions within the Synod is the Binder's Conclave, which enchanted a focusing crystal for use at the Oculory of Mzulft. Both the College of Whispers and the Synod have attempted to form alliances with the College of Winterhold, but despite pressures the independent organization has remained neutral. In 4E 201, the Synod attempted to use the Oculory of Mzulft to locate artifacts of great magical power, but the Eye of Magnus prevented the Oculory from working correctly. The Eye was being held at the College of Winterhold at the time, which may have embittered relationships with the Synod.
A Synod researcher, Yvonne Bienne, authored a catalogue of weapon enchantments and a catalogue of armor enchantments, both of which widely circulated in Skyrim around 4E 201. She is known to have taught students in the art of enchanting.
