\o/ Serph hasn't had as much to do with the recording of things, but he was there when Jayce was attacked (cw: for heavy gore and monster eating in the thread) after experimenting with the runes found around the land. The main outcome being that Jayce attracted the attention of Something Else out there that can control the monsters and can drive someone investigating the runes mad. Serph has mentioned this when discussing the lack of sentient life with others, so it wouldn't be too hard to get him to share that information with Zero too.
