Jack and Diana went directly to the underground ruin under Malva's private warehouse. When Severus saw Jack again, he was surprised but not as unpleasant as the first time they met.
"Your Majesty, what brings you here?" Severus asked.
"Good Severus, I'm here to finally relieve you from this never-ending task," Jack announced.
"Haha, Your Majesty truly likes to joke."
"No, seriously. I'm here to take back the Boundless Cache for the kingdom."
Severus gave Jack an exasperated expression. "Your Majesty, you do know that we only have one artifact powering the rune diagram now, right? If you take the Boundless Cache, we won't be able to…"
Severus stopped when Jack showed him the Portal-closing Stone. His eyes were wide.
"This… How do you come to the possession of this stone?! Our faction's archive said that this stone can only be produced in the underworld."
"Hehe. I got it from the underworld, of course," Jack answered with a grin.
