Quote from after Shaeonanra and Aurang finish burying Titirga in the well of Viri:
"They had no inkling of the greater violence their sorcery had unleashed."
Could that be referring to the nuke that Kellhus exhumes 2000 years later? Possible that it was given to nin'janjin or hidden by other long-dead Inchoroi and the two lovers somehow unearthed it from some hiding place?
