I heard an easter egg in the form of a conversation between Calcelmo and his nephew in Markarth keep. It was yet another starwars easter egg where Calcelmo was telling his nephew," next time for sure" and that he "needed him" this was copying the beginning of star wars a new hope when luke wants to leave and join the rebellion. I dont know how many times this will happen, I have only heard it once, despite trying to wait an listen.
