First I guessed the Lost Lord might be Howland Reed. Then I noticed the ressemblance between past events that occured in Volon Therys, Volantis and Sar Mell iirc (the Turtle War and the Spice War) and the Reyne and Tarbeck rebellion. Bell ringing. Now I cannot decide if JonCon is The Last Lord Tarbeck or young inversion of the Merryweather Hand of the King. If some of you guys with more free time than me could help... You all are brilliant minds.
