slightly, remembering how close he had just been to that planet, even if it hadnât actually been real.
Had it?
âSomeone could have told them,â said Sarah.
âYeah,â said Marco. âBut then they spoke about Sirius B.â
âWhatâs that?â asked Sarah.
Leo spoke up. âThe object we saw orbiting Sirius.â
Marco nodded. âAnd it wasnât photographed until 1970. But the tribe knew about it long before then.â He met Leoâs gaze.
Leo smiled a little. âBecause they had been told by my people.â
Something nagged at Marco, some other detail from the show that he couldnât quite remember, something even odder than the rest. He wished Nacho were there. His brother would know.
Sarah asked Leo, âBut that was it? They told the tribe some stuff and went back home?â
âNot exactly. My people were on a mission.â
Sarah glanced at Marco, who asked, âWhat kind of mission?â
âOur planet is very similar to Earth,â said Leo.
âYou already showed me that.â Sarah looked down at the sand.
Marco wondered if she had the same weird feeling about Leo that he did. Because the boy was obviously on some kind of mission himself.
Leo said, âYour planet has limited resources. Which your people are beginning to realize.â
Sarah said, âNacho explained to me about the exoplanets.â She bit her lip. âHe would be excited to learn that itâs all true. But heâs not here.â
Marco frowned. His little brother was there, just not able to walk or talk or be with them, because he was frozen. His frustration bubbled up. âCan you get to it? Tell us why my brother is frozen and you canât let him out?â
Leo glanced over at Marco and sidled away from him slightly. âThe history of my people is getting to it.â He reached up and wiped sweat off his face, then took a deep breath. âThis is what you may find hard to believe. Because your civilization isnât there yet. But my people created the progenitor .â
âWhatâs that?â asked Sarah.
âIt allowed us to replicate whatever we wanted.â Leo walked down toward the water. He took off his shoes and let a wave lap up over his feet.
Sarah followed him. âYou probably shouldnât get that close to the water.â
Marco caught up too. âI donât get it. You can just make whatever you want? Like the grilled cheese?â
Leo backed away from the water a bit and stepped back into his shoes. âThe food center on my ship was created from the same technology.â
Sarah asked, âWhat else could you replicate besides food?â
Leo shrugged. âObjects. Plants. Animals. Whatever we chose.â
Marco thought out loud, âSo itâs like a 3-D printer.â
âOnly times like a million!â added Sarah. âHow cool is that.â
âThere were problems.â Leo scratched his head. âIt was so much power and caused fights over who should control it. Eventually, the leaders decided it was too much power for anyone to have. So they split it in two.â
Sarah snapped her fingers. âYou left half on Earth.â
Leo smiled at her. âYes. We entrusted the tribe with it.â
âBut why give it to them?â asked Marco. âI mean, seven hundred years ago there were other more advanced civilizations.â
âBut we werenât seeking the most advanced .â Leo held up a finger. âDo you know one of the most important pillars of that tribal society?â
Marco shrugged.
âHarmony.â Leo explained, âThe power to create walks hand in hand with the power to destroy. We needed a hiding place for half of the progenitor. But not just to keep it safe. To keep your planet safe from its powers. In the wrong hands, it could be a weapon.â Leo looked down at his feet. âAs we learned.â
âIs that what
