Jacob took Aven to a remote section of the forest before they were out of everyone's view. He asked, "Now, tell me, what were you withholding before?"
Aven's heart sank when she heard Jacob's forceful tone, "We didn't withhold anything from you, Sir Viper. You had seen the map yourself, and now you'd watched the door yourself."
"Yeah, but you said the is within mountains. But you never said it was inside a mountain! Do you plan to bury us all? Furthermore, I've studied the runes, and they seem to be not sealing the door; instead, they are sealing a certain recess on that door. For example, like a keyhole!" Jacob revealed while his icy cold eyes were looking deep into Aven's eyes.
The moment he said 'keyhole,' her pupil dilated, and she quickly answered, "But we don't have any key, and unlike Sir Viper, we are no expert in runes, so how can we know this location?"
Inwardly she was cussing herself, 'Shit, so there was a keyhole in that door as well?!'
