He was prompted to speak about Sonichu at the table, and was showing us the binder he brought around. I believe he talked about some of the lore, but I really am not as familiar with it as I used to be. @Jaiman might be a better source on it, since he was there as well and probably could go into more detail.What in particular did he say about Sonichu? Anything noteworthy?
And was it in response to people asking about it, or did he just start rambling about Sonichu by himself?
