The Wise are organized into 12 Domains—essentially ‘departments of state’. Each of these Domains is headed by a Grand Sapient. The Grand Sapients are collectively known as the “Twelve”. The diagram on the right shows each of the Domains and the associated duties that each is required to carry out. The Twelve not only match the 12 lunar months—one of the reasons the Wise use the moon-eye as their sigil—but also thus to the twelve calendar months whose colours they match.
The diagram above shows the hierarchy of the 31 Sapients of a Minor Domain. A Major Domain has 63 Sapients.
