The loose association of Darujhistan residents connected by circumstance, mutual interest, and Kruppe's apparently artless management of their interactions. Kruppe, Crokus Younghand, Rallick Nom, and Murillio are not a formal organisation - they share a tavern, a neighbourhood, and an accumulating series of entanglements that Kruppe navigates with more deliberateness than his manner suggests. The Circle is less a group than a social fact: these people are in each other's lives, and Kruppe has ensured that their combined capabilities are available when the situation requires them.
