Warren immediately knew what the Patriarch wanted. He must have been asked to remain behind for the materials. Once they arrived at K18, the construction work would begin, and building materials would be needed.
Warren and Himmel Soan had discussed it before. Himmel Soan had told Warren that he would take care of it. Now that the portal was about to open, the Patriarch instructed him to stay behind. Warren knew the Patriarch must have come up with an idea.
However, the opening of the portal was so sudden. Everybody was astonished when they heard the news. They had a hard time digesting the news.
Even now, they still couldn't fully believe it. The portal would open in three hours. That gave them little time to prepare.
Charles was the most surprised of them all. Himmel Soan had told Warren about it, and he was done being surprised, so he didn't show any reaction.
