Viserys might be a lot more stable here. Especially if he is Raised by Blue Dragons who are Lawful Evil with very good Community and Family dynamics.
I generally prefer the Pathfinder Dragons to the D&D Dragons. Pathfinder has the Outer Dragons after all..... Maybe F-Aegon the Blackfyre heir...

Metro and STALKER meet the Apocalyptic Criteria for the USSR fine but not the Aforementioned "Nostalgic Golden Age".
The 1920's Post Revolutionary Avante Garde and Utopian thinking were One of the Soviet Unions Golden Ages.....
The 1970's were the other.....
Maybe a Mix of the Two Eras...
Maybe if Quervo Jones had lived up to his Utopian Spiel rather than being an Opportunistic Predatory Psycho?
The stuff that Girl Snake rescued from the Surgeons said about LA being free vs the Mainland maybe could have been explored further instead of a throwaway line before bing shot...
