Medunamun (c. 103 BCE – 48 BCE), also known as The Ibis, was an Egyptian member of the Order of the Ancients who was installed as the Oracle of Amun in Siwa, Egypt by the Pharaoh Ptolemy XIII in 49 BCE. Since the purported impetus for his appointment was for the Pharaoh to consolidate his hold over the remote, dissident town, Medunamun was derided as a false oracle by his enemies, including the Medjay, Bayek. In reality, his motives for seeking the mantle of Oracle were more covert, for his true interest was in an Isu Vault that lay beneath the Temple of Amun. Under Medunamun's injunctions, the villagers of Siwa were subjected to extortion and arbitrary detention and were the victims of rampant atrocities committed by the town soldiers. Protests were met with violent reprisals, often against entire families, with whole neighborhoods being razed to the ground. For his part, Medunamun was loyal not to his king, but solely to his Order, and endeavoured only to unseal the vault beneath the Temple. The Ibis thus played a key role in the death of Bayek's son Khemu in 49 BCE during a botched interrogation of the Medjay. For his complicity in Khemu's demise and his abuses of power in Siwa, Medunamun was assassinated by Bayek in 48 BCE.
