Do you think Varys will die in the explosion of King's Landing? Or what future holds for him in later books?
Probably getting ‘sploded in the Great King’s Landing Kaboom, I’d guess. Varys managed to escape the detonation of the cache of wildfire under the city once, but I don’t think he’ll be as lucky the second time. Varys had subtly encouraged Aerys II’s paranoia in the last years of his reign, but did nothing to stop (or, perhaps more likely, was completely unaware at the time) of the most deadly expression of the king's madness, in the accumulation of the many, many jars of wildfire under the city (and has, apparently, been doing nothing about them since, although it seems wildly unlikely that he has no idea at least of the partial extent of the wildfire). Now, for all his years of careful planning, his smooth assurance that he’s created the perfect king, Varys will find himself caught between the legacy of the Mad King and the coming of his daughter; he who had thought he could move Daenerys as he would to suit Aegon’s needs will find that Daenerys is far from the malleable pawn he had imagined. The whole city, from Aegon VI’s shiny new court to the slums of Flea Bottom, is going up in a sickening green explosion, and Varys the master plotter is going right up with it.
