This is based on 'Gensokyo's Heart' story, and I have asked the original author, AntagonistChan, to re-create the story. It will mostly follow the original's events, but there will be changes to fit some of the 'abnormal points' in the original story. Thank you AntagonistChan for giving me permission to write this one.

Without further ado, let's begin the first chapter of Heart of Gensokyo!

Evolution Master. The only one of a kind existing in the Swarm. His title.

Looking at flesh to find potentials. Consuming essences, analyzing and applying them to the Zerg. Making them better. His work.

Improving the Swarm, evolving it and seeking perfection. His purposes.

Lesser than even a beast if there's no overriding will. His thought of himself.

Abathur. His name.

Created by the Overmind. Brood of one. The instrument of Overmind's will. Designer of Queen of Blades.

Purposeless after the Overmind died. Retrieved by Queen of Blades and taken under her command. Developed more types of Zerg. Experimented on Terran provided by the Queen. Continued working even after the Queen de-infested.

Now, working for the new Queen of Blades. Still working for the Zerg, but no Terran experiments. Fine to him. Essences found everywhere. Just have to look closely.

Current workplace: Evolution Pit inside of a Leviathan.

Current location in space: Above Skygeirr Platform.

Current time: After fighting Narud.

Queen of Blades injured. Placed inside of a Spawning Pool for heal. Zagara taking control of the Swarm. Can't control him. Still continue work.

Not for long.

Zagara looks at the burning Platform as the Zerg creatures are still on it. She then talks to Stukov: "The Queen sensed something before she passed out. Something… different."

Stukov asks in confusion: "Different? Another Hybrid?"

"No. Neither Zerg, nor Protoss. A rift in space."

Stukov just shrugs: "Well then, maybe a leftover of Narud's work. Just go find it."

Izsha halts them: "We have to wait for our Queen to give the final decision."

'Do it.' Kerrigan's voice echoes in their minds. 'We can't allow his work to be left unattended. However, to minimize the damage to the Swarm in case if the danger's still there, you are leading this operation Stukov. Send your Infested there.'

Stukov bows lightly. "I hear you, Kerrigan."

Half an hour later

"Looks like they're correct. A rift in space." Stukov speaks to himself as he observes the crack that's placed in a hidden chamber with Protoss designs inside of the platform. "That looks like a Protoss gate. Definitely Tal'darim is up to something with this."

'So it's just a portal. Can you feel where the other side could be?'

"Wait a moment…" Walking closer to the rift, the Infested Commander looks through it, to see a very, VERY green land, with a very clear sky, no signs of industries or modern age structures can be seen. However, judging by the flying birds, the place is…

"The rift connects to Earth?" Stukov asks in surprise. Never once would he think that a portal could lead to Earth without the UED noticing. But, he didn't remember, in his past life, that a place this clean could exist.

'… I will be the judge for that once I recover. Zagara, position some of the Zerg to guard the gate. Stukov, retreat back to the Leviathan, we will discuss more about this.'

"Will do." 'I will comply.' That's Stukov and the Zerg Queen's responses, respectively.

Time skip

Infested Terrans. Squishy. Not worth to upgrade. Focus on Mutalisks. Making them faster…

"Abathur…" The Queen of Blades, in Evolution Pit. Orders. "If I remember right, you have some knowledge about Xel'naga artifacts, right?"

"…Yes."

"Good. Come with us. We have something that could be the work of one."

Don't want to leave. "Can't bring here?"

"No. It's a rift. No artifacts are nearby, but it could be related."

"Unimportant to me."

"It is now." Eyes glow threatening. "Don't forget that you're still alive because you are still useful to me. You DO want to stay alive, don't you?"

… Can't deny. Can't back away. "Will…do. Can't improve the Swarm if deceased."

"Good." Eyes now normal. "We're leaving in a moment. Also, start packing your project." Knew? "Don't be surprised. I know everything happening in the Swarm. That project of yours won't be able to stop me, but it could be a fine additional to the Swarm. Now, get moving." Completely leaving the room.

…No more reasons to hide. Must prepare immediately.

Time skip

"Not Xel'naga." Just a rift in space and time. No Xel'naga involved.

"Really?" Stukov asks in confusion. "What else could create a rift this big?"

"Could be Narud's work. That bastard has the power to do so…"

Zagara: "But he could just corrupt this world and get the uses from it. From the looks of it, this place is completely untainted."

Kerrigan glances at the Queen in surprise. "I see the work of Abathur has grown fruits. Yes, that's completely illogic for Narud to leave a portal like this… but then the Tal'darim has built the gate to protect it… why?"

'Unfortunately the Tal'darim survivors have run away, and there's no more left alive.' The voice of Izsha echoes in everyone's mind.

"Good." Gazes at him. "Pure essences to collect. Improve the Swarm."

"Hm… that could work. Abathur, your new order: go through the portal, get essences but do not infest the place. We don't want the UED to notice us."

"That's a magnificent plan, my Queen. But, who's going to help improving the Swarm? I can say you can do it, but Abathur is the expert in that."

"I know what I'm doing, Zagara. The Platform belongs to us now, and we have destroyed all Narud's researches, so the Dominion doesn't have a reason to return here."

Stukov disagrees: "That could be, but remember now that they have targeted this place as their enemy's territory. They could return with greater forces to destroy us."

"That's the future matters." Then everyone sees a large shadow behind them, as they turn back to see a somewhat smaller Leviathan floating down. "Ah, that's your things right, Abathur?"

"…Yes." Not everything.

"Wait, what is that? How come is the Leviathan so small?" Stukov asks out loud in surprise.

"That's Abathur's secret work. I told him to bring it with him. He going alone would get him killed instantly." And then a small Ultralisk erupts from the ground. "That's your last one?"

… "Yes."

Kerrigan concludes: "You know your objectives, get it done. Stukov, the platform is yours. I will call Dehaka to tell him to help you as well. Zagara, you stay here as well. I'm going to find Jim alone."

Chapter 1 end!

Yeah, I'm not believing that Kerrigan could somehow know Gensokyo. Also, naming a random planet is not my style.

For now, that's it. I will write more soon, but not after updating my other stories. See you all later!
