Portal Network
Alex and Caleb visit a portal space which is configured nearly identical to their home universe. When they travel to where Earth should be, instead they find a supernova remnant; the sun has become a neutron star and Earth has been destroyed. Alex theorizes that the Metigens are manipulating stellar evolution and possibly space itself.
Valkyrie locates a star undergoing unnaturally rapid evolution, and they discover an artificial structure where a Metigen operates multi-dimensional machinery to fire ultra-dense orbs into the star. Abruptly the Metigen and the structure depart as the star’s core begins to collapse. The Siyane flees seconds before the star goes supernova.
The next portal space holds a frozen, seemingly empty planet. While they are exploring, an alien appears. It indicates for them to accompany it, then reveals a hidden passageway in the ground. As they begin to descend, Alex’s connection to Valkyrie is cut off. The alien communicates via touch that they are traveling to a refuge protected by a barrier. Mollified, Alex and Caleb agree to spend a little time below.
On the Siyane, Valkyrie is visited by a Metigen named Lakhes, who tells her Alex and Caleb are safe and the species living here is no threat to them. Somewhat reassured, Valkyrie decides to wait for their return.
They find a thriving civilization beneath the surface, and learn the species, called Taenarin, was brought here by Lakhes when their homeworld was threatened. Their spiritual leader, the Caomh, retains the memory of this exodus, which occurred hundreds of years ago.
The Caomh has the ability to absorb memories and transfer them to others via touch. In this way Alex and Caleb experience the memory of the Taenarin leader in their home universe, Amaranthe, when Lakhes appears to warn him his planet is to be mined for resources then destroyed by a species known as Anaden. Metigen ships evacuate the Taenarin to their new home, and Lakhes vows to hide and protect them.
Afterwards, the Caomh speaks to Alex alone. She shares that Alex and Caleb both have another lifeform living inside them; Alex realizes she means fragments of Akeso. She also expresses concern over “the hole” in Alex’s mind—the absence of Valkyrie, and Alex’s growing need to join with the ship. Alex tells Caleb about Akeso but not the rest. Later that night, she awakens from what Caleb believes is a nightmare, seeking sexual comfort as a substitute for another need.
The next day they return to the Siyane. Alex quickly slips into the walls of the ship, admitting to herself that she craves the experience.
The next portal space is highly unusual. The first star system contains 258 planets orbiting in 3 sets of concentric circles. Each planet is being harvested by hordes of machines. They visit the surface of one of the garden worlds, which serves as a planet-spanning orchard, but are soon attacked by harvesting bots and must depart.
A host of vessels ferry the resources collected out of the portal space and traverse the enormous master portal, which they now know leads to Amaranthe. Alex convinces Caleb they should sneak in with one of the vessels. She slips into the walls of the Siyane as they near the portal.
The portal denies them entry, sending the Siyane ricocheting off into space. The force of the impact causes Valkyrie to malfunction and Alex to have a violent seizure. The Siyane comes under attack, and Caleb is unable to wrest control from Valkyrie to escape. Mesme reaches them, surrounds the ship and transports them to Portal Prime.
Alex regains consciousness, and they effect repairs to the Siyane while arguing about what had transpired. The argument is interrupted when another Metigen arrives and confronts Mesme, who refuses to turn Alex and Caleb over or shut down the Aurora portal. Lakhes appears and takes Mesme’s side, forbidding any harm to the humans.
Alex tracks the departing Lakhes through sidespace to one of the other portals, and the Siyane follows.
She encounters an enormous structure built of light waves. Numerous Metigens are in residence. She comes upon Lakhes conversing with another Metigen about a portal species. The two agree to allow the species to kill itself off then shut down the space. Valkyrie figures out the species is the Khokteh. Lakhes confronts Alex, refuses to spare the Khokteh then forces her consciousness back into her body.
They return to the Khokteh homeworld to find it in ruins. When Mesme shows up, Caleb delivers an ultimatum: they refuse to play whatever role the Metigens have planned for them unless their questions are answered. Mesme complies, explaining that the Metigens do not possess the fierce spirit necessary to wage war. The portal worlds allow them to study many ways to fight and kill, in the hope they might discover a way to defeat their oppressors. Mesme then informs them their presence has been requested at home and departs.
They find Pinchu, injured but alive. Alex pleas with him to make peace, as his entire universe will be obliterated if he does not. She and Caleb agree to help him broker a peace with the other colonies.
They proceed to do exactly that, then inform the Metigens the Khokteh are under their protection. In return for a guarantee of the Khokteh’s safety, they will help the Metigens in their war in Amaranthe.
Mesme declares their terms acceptable, but says there is no war today, only the dream of a future one and confirms the Anadens are the oppressors. When Caleb asks what the Anadens are, Mesme’s response is, They are you, and you are they. Humans are the genetic recreation of the Anadens, engineered so the Metigens could study their enemy.
