Found a typo when talking to the red prince to get him to join.
One of the responses (#2 of 3 for me) is "Ask him a Dreamer is exactly" figured it is meant to "Ask him what a dreamer is exactly"
His previous line was "Alas, it's the latter that is eluding me, despite the ministrations of meditation. There's nothing for it I suppose, but to try anew, or vacate this seaside spot and embark upon the search for a Dreamer." if that helps
