History was destroyed and once he is over being devastated at the loss, he will be furious. He will absolutely not believe Cain had anything to do with it, given Circe actively tried to get him to go away and has been trying to edge in on his role as historian with her "oral history" for a while now, and he's been working with Cain for a few days at that point and believes Cain only has respect for history and writing.

Less fury-inducing, he picked up a handful of people interested in learning from him! And so many of the new Foundlings show respect for him and his work! This is encouraging to him in a way he hasn't felt in a long time. He will be spending the next week working with them to start creating new tablets to replace what was lost, and spreading as much ire about Circe as he possibly can. How dare she.
