Chapter two (HTtBR:revision two

298 AC.
Harry's time as Master of Coin had continued to be spent wisely. He had continued participating in tourneys and won a lot of gold dragons in the process by winning and also gambling with wealthy idiots. Harry also continued falsely reporting the tax income of the Reach and Dorne to cheat the Iron Throne and House Lannister out of money. Both regions were far more wealthy now and primed for war or rebellion. Not only was Harry not caught or punished, but he was rewarded.
Harry was made acting Hand of the King when Jon Arryn was murdered by the Lannister's and Lysa Arryn; until Lord Eddard Stark could accept, and much to the Lannister's and Stannis' anger. Apparently, the lackwit Queen extorted Lysa into doing the deed by threatening to expose Robert 'Arryn's' bastardy.
Harry didn't care a bit. He just began working to better the Nine Kingdoms and began spreading the 'rumor' that Lysa Arryn murdered her husband and kept spreading the 'rumor' of Robert's bastardy to weaken her support in the Vale. Already there were plots to remove the two from the Vale, and Harry stopped Robert from declaring Jaime Lannister the Warden of the East and had him let the sickly, weak, lackwit bastard keep the titles and have Lord Yohn Royce do the actual work. Thankfully, Robert agreed and didn't anger and divide the Vale. Harry did that.
Harry wanted Jon's rightful heir ruling the Vale. Jon was great man and deserved a true heir, but Harry would at least ensure his legacy wasn't stolen by a whore and Baelish's bastard. Harry would do that for the man out of respect.
