Polonius Krai is a 17 year old student at Garreg Mach Monastery and the son of a rich merchant family. He comes off as friendly and approachable but is painfully honest, to the point of being considered rude by others. He easily gets bored with everyone and won't start a conversation with another person unless forced to. He is an up-and-coming scholar and while he may be knowledgeable in the theoretical field, he is much worse at using it in practice.
