Thomas looks puzzled "My brother I saw him at his wedding, what was the girl called hmmm Mary-Anna Monman"
Balin's jaw hits the floor at the mention of his name, he quickly composes himself and looks at Ana almost as if trying to send a telepathic message as he shuts his book with a slam.
Hrgach looked over at Balin as he slammed the book closed. “What?” he snapped at the halfling. “Somethin’ significant in that? Who’s Mary-Anna Monman?”
"Wait," Ana says. "Azgalan's family name? The thing in the cave is a person, or related to people living around here?" Turning to Balin, "And when did William get married? He's still alive. How did Thomas go missing and never get found?"
“Wait. Great-grandfather?” Hrgach asked. “That puts the boy down there nearly a century. So who was this Azgalen, what’s he become, and what’s his interest in the boy?”
Balin looks shocked at the hobgoblins statement"That can't be right I grew up with him. Maybe we should head up to the manor and see if his Lordship is in, maybe he can explain."
