tywin lannister was dead , butchered by his dwarf son ; his corpse had stunk so badly that no one had been able to enter the great sept of baelor for days afterward ; the lady of the eyrie had been murdered by a singer ; littlefinger ruled the vale now , but bronze yohn royce had sworn to bring him down ; balon greyjoy had died as well , and his brothers were fighting for the seastone chair ; sandor clegane had turned outlaw and was plundering and killing in the lands along the trident ; myr and lys and tyrosh were embroiled in another war ; a slave revolt was raging in the east .
