- "The Magisters make a great show of choosing the Prince of Pentos from the Great Families, and granting him the powers of trade, justice and war. As long as he checks with them first."
- ―Jorah Mormont.
The Free City of Pentos is nominally ruled by a Prince, but it is the magisters who truly hold the power, as it is they who select the Prince from the Great Families of the city. The Prince is powerless to act in matters of trade, war, or justice without conferring with them first. Also, should a crop fail or a war be lost, the Magisters slit the throat of the current Prince and select a new one.
