"If I don’t go back, then – “
“I know,” Greg interrupted. “I just wanted to be sure.”
Nick turned and walked to the far side of the room where the time device was held. He stood in front of it and stared. The time device was a simple-looking ring in the centre of the room, which needed some clearance on either side for it to open a portal. Nick had taken it from the Mother-ship, which took some doing without being seen. Then assembled it here, inputting the coordinates to where he wanted to travel.
The screams outside continued and Nick glanced towards the sound. He hated what the Na’en had done to this world, just so they could take it from the inhabitants. They needed somewhere to live and had chosen this place. He had to find a way to stop them, and this was the only way he could think to do it. There had to be a way somewhere in the past to stop the Na’en from getting to this point in time.
“Are you sure you don’t want to come with me?” he asked.
“You know I can’t,” Greg answered. “I can’t go back in time. I can’t meet my ancestors. I must try and keep the line going. And you have to start it.”
Nick nodded. He knew that Greg wouldn’t be joining them, but he felt he had to ask anyway.
Nick turned to his son

as the portal opened. “Time we should be going,” he said.
“Where we going?” Cai asked, not understanding what was happening.
“We are going to a place far from here,” Nick tried to explain. It was hard telling his three-year-old son what was really happening. He was too young to understand yet. Nick would tell him the truth one day, when he was a little older and more able to understand.
“Away from all the screaming?” Cai asked.
Nick nodded. “Yes, away from all the screaming.”
“Good. I don’t like it when they scream.”
“I don’t either.” Nick turned back to Greg. “This will get sorted out, “ he promised. “I won’t let it come to this.”
“I hope you will,” Greg answered with a weak smile.
Nick turned back to the portal and activated it. There was a flash of light and a swirl of wind that filled the room, picking up the dust and dirt from the floor.
“See ya around,” Nick said, smiling, waving a hand towards Greg.
“I doubt it,” Greg answered.
Nick picked up his son and began to walk towards the portal. Within moments he had disappeared. The portal closed moments later and Greg was left staring at the time device and the wall beyond.
