Keith is widely renowned as one of the world's best linguists, and so Claude and Rena seek him out to help translate the Ancient Text from Krosse Cave. However, they have difficulty gaining access to him. Keith does not decipher the document until much later in the game. In Bowman's solo ending, Keith will speak to Bowman about the document, and say that it tells a story about an ancient paradise. He is startled when Bowman correctly guesses that the ancient paradise was named Nede.
