Background
He had been exploring the Castlekeep Ruins near Daventry town when the Cataclysm hit. Connor vowed if was all within his power, to liberate the man from his vile condition. The writer was in the castle courtyard, and may have discovered or was close to discovering the secret magical wall, hiding the chest filled with gold. He at least was very close to the secret niche.

But there is always the possibility, and the circumstantial evidence may even support it..
