So it's actually been awhile since I have last seen Jeo Brock, but I spoke with him two days ago. Indeed, he knows Pherra, and knows that she still lives in West Terredon.
Furthermore, I told him everything about our meeting with the Society Dungeonmaster Skylar Meredyth. And he promised that he would set out to collect as much information as possible about Tom Kearney.
I've gotten in touch with Pherra, herself, who agreed to meet with me over this. I am setting out for West Terredon next week.
