Prorok (also called The First) is the Kahini (Prophet) leader responsible for the creation of the Covenant, ending the long cycle of war with the Sangheili. He was the first Prophet of Truth and sought immortality through both legend and transsentience. With the construction of the Luminous Key, he attempted to upload his mind and become an artificial intelligence construct. Whether or not the resulting AI was in fact Prorok and not a second being is a matter of debate amongst philosophers, with Sangheili historians classifying both entities as one in the same while Human historians are less likely to out of a disbelief in transsentience.
