There was no future for them here— the mana on Earth had a very different feel compared to their home planet. And none of their children could survive here.
Damian told all pigmen and his companions to gather outside once they had all prepared. Everyone was already ready to depart from Earth. Then he went to the island where he had left Sulthar and the other three. He was glad to find the three near the island; they had not wandered off.
"Take this—it will contain your mana for a while," Damian said.
