The division of power across the cosmos had long been established. The Green Lantern Corps' mandate to "protect universal peace" was largely ceremonial in practice—there were territories they couldn't reach, and many they didn't dare touch.
The Kryptonians in their heyday. The father and son of Mongo. And now the Rachi Swarm—all beyond the Corps' reach.
In the main brain's reading, Thea was here to recruit them. The Rachi had grown wild and ungoverned; every intelligent civilization in the galaxy resented them for it, and they were currently the only major power in the cosmos without an overlord. That left them exposed in ways the main brain didn't like to think about.
But the main brain didn't bow its head on impulse. It wasn't about to swear loyalty on the spot—it wanted to see first what this "Soul Sovereign" could actually deliver.
"Honored Supreme," the main brain said carefully, its tone deferential to the point of abasement while the subtext was crystal clear: Show me results before I sign anything. "The Rachi Swarm would be honored to receive your favor. Please grant us one small request first."
Thea held up one finger. "Right now, on this fingertip, there is a pure soul—no memories, no history. I know you can't see it. But if you bring me one of your people, I'll demonstrate in front of you."
She'd originally come here intending a transaction. But the main brain had read it as an offer of allegiance, and she saw no reason to correct the misunderstanding.
To the main brain, the logic was impeccable. The Soul Sovereign. What a title. Announcing yourself like that and not being struck down by cosmic retribution meant the universe itself had recognized the claim. A being like that didn't run a shop. It didn't peddle goods. It granted favors.
The main brain considered for a moment, then sent a signal. A winged Rachi flew up to join them.
Siren had been cycling through a substantial volume of souls in recent months, and those study sessions had finally paid off—Thea now had a working method for inserting a soul fragment into a living body. It was a significant step forward from her previous approach, which had been strictly a one-way process.
Doing it with a complete human soul was extraordinarily complex: psychic architecture, physical integration, memory encoding—every variable fought every other variable. She hadn't solved that one cleanly yet.
But the Rachi were a different case entirely. Their soul presence was so faint to begin with that a single look had been enough to map their internal structure completely.
Rachi physiology was built for evolution—countless advantages, but the same rapid-cycle gene expression that let them adapt so quickly also interfered with soul development. To put it plainly, they were too casual about it. For long stretches of their history, most individual Rachi had drifted through their lives in a half-aware fog, entirely dependent on the main brain for coordination.
Possessing a soul, holding memories, and thinking independently—these were the markers of true sapient life. If the Rachi gained souls, they could be called they instead of it—the most significant transformation in their entire species history.
She didn't use Earth soul fragments. For reasons tied to the Entity of Life, life originating on Earth was intrinsically a tier above alien life in her system—even a fragment from someone deeply unpleasant wasn't appropriate for a Rachi.
But her research had yielded something workable: synthetic soul shards. Magical energy sculpted to simulate the soul's resonance frequency, with hand-crafted memories loaded in and then wiped clean, then stabilized with a small application of divine soul power. A blank template.
She sorted through her stock and selected one—a ten-year lifespan distillate, already cleared of all memory imprints, as close to neutral as she could make it. She located the key meridian nodes and spoke a brief command. The shard followed the soul pathways and drove itself home.
Invisible ripples moved through the air. The main brain—with its extraordinary psychokinetic sensitivity—felt the shift immediately, and turned a cautious gaze on its tribesman.
The Rachi that had received the soul blinked in confusion. Several long seconds passed. Then something changed in its eyes—the slow, bewildered dawn of I.
The main brain watched in silence. After a long moment, it looked back at Thea. "Please give me a moment, Your Eminence. I'll return shortly."
It swept the newly-conscious Rachi up in its field and retreated.
Thea didn't stop it. As the main brain, its own personal consciousness was the most strongly developed of any Rachi—the moment any tribesperson broke free of its direct control, it felt the shift instantly. More to the point, a subject with too strong a self-will was a threat to its rule, and it would not allow that.
Whatever it did to that newly-aware individual—dissection, vivisection, study, elimination—that was its own affair. Thea held her position in the air and waited.
The main brain returned quickly. Its deference had increased by a noticeable margin.
It chose its words with care. "That soul is... too powerful for our use. Would you happen to have anything more suited to our species' specific characteristics?"
Thea nearly laughed out loud. The creature was afraid a strong-willed tribesperson would threaten its authority. And this was already a degraded synthetic copy—it wanted something even lower?
Normally, simplified versions of anything were easier to produce than complex ones, and she'd have been perfectly happy to provide something lower-grade. But her objective had shifted. She no longer wanted a transaction. She wanted the main brain itself.
"Stop dancing around it," she said. "I have no interest in ruling your swarm. Instead of weakening your subjects, why not strengthen yourself? Do you want to become a true sapient being—shed that body, walk under open sky, lead your swarm to victory after victory?"
The words landed quietly. In the main brain's ears, they hit like a thunderclap.
Temptation. The most dangerous kind. The main brain wasn't naive—if it opened its psychic core, Thea could do anything in there. It might not even know how it had died.
"Your swarm remains yours," Thea continued. "The only difference is that you could leave this barren rock. You could move as an intelligent being under the open sky, travel through space, and see things you've never had the body to see. Is that a hard choice?"
The risk was real. The lure was greater.
After a full ten minutes, the main brain made its decision. "Your Eminence. Please—come inside. Let us speak properly."
The psychokinetic projection dissolved into scattered particles. The Rachi guards below parted, opening a path.
Thea walked through the winding stone tunnels and finally came face to face with the main brain's true form.
Inside a translucent membrane of stretched tissue lay an enormous brain—the size of a small hill—resting in the silence of its stone chamber. The stillness carried the weary weight of something ancient. Psychokinetic energy of near-physical density hung in the air around it—not a display of aggression, simply the overflow of a power it could no longer fully contain.
It had four limbs. They had atrophied to near-uselessness—decorative more than functional. Three feed tubes extended from the rear of the brain, pumping a dark green fluid in a slow, steady flow.
"You're dying," Thea said, without preamble. She had taken one look and seen the whole picture. Even with the fluid sustaining it, this creature had only a few years left.
Of course. Without a soul strong enough to anchor it, the neural mass had been slowly unraveling over time. It would die quietly and unseen, and a new brood-brain would emerge to consume and inherit everything it had been, carrying the chain forward. That had been the iron law the Rachi had lived and died by for uncountable millennia.
That had been the law until today.
Facing a death that had always been coming—now finally close enough to smell—the main brain dropped every pretense and opened its psychic core.
It chose to surrender.
