What creatures guard Azkaban prison?

Dementors guard Azkaban, the wizarding prison in the North Sea. These hooded wraiths feed on human happiness, chilling the air and draining hope—ideal jailers because prisoners become too despairing to resist. Their most feared act, the Dementor’s Kiss, removes a person’s soul, leaving a living shell. The Ministry once employed Dementors to maintain order, but the creatures later sided with Voldemort, showing the danger of relying on fear. Memory tip: Azkaban feels “dementing,” so think Dementors. By contrast, Basilisks are giant serpents in the Chamber of Secrets, Thestrals are skeletal winged horses that pull Hogwarts carriages, and Grindylows are water demons of the Black Lake.
