I think it should be noted that FR's Ruler and lord of Golden Farrow (the last remaining region in FR) eventually joined Asylon anyway after the city went rogue. I did not notice any real effort to even keep GF; it's like we just waited for taxes before jumping ship into a different realm (D'Hara for my character, Asylon for the last FR Ruler). That makes everything seem like a realm merger, personally.
