Pensieve

A Pensieve is an object which allows for the sorting and reviewing of memories. The Pensive of Hogwarts is used by the headmasters to review specific memories. Not much is known about its creation except that it is made of stone, carved with Saxon runes, and it is older than the school itself. According to legend, the Pensieve was found by the school’s founders half buried in the ground, and it has become an invaluable tool for headmasters and headmistresses.
