"Of course it was Snape! Who else could it be?" Ron exclaimed.

"Oh, come on Ron. Snape's a teacher. Dumbledore wouldn't have hired him if he was evil," Hermione said. The group was walking along the corridor, Harry still in his quidditch uniform, and attempting to get the taste of Snitch out.

"Hermione, correct. Snape not possessing motive to kill Harry. Claim illogical," Abathur stated. Personally, he thought the argument quite stupid. The logical move would have been to ignore the aggressors and prevent the attack from occurring again by other means. Or eradicate or infest everyone around to prevent any risk, but that wasn't feasible yet.

"Then what was he doing during the match? Why else would he be looking directly at Harry and muttering?" Ron continued to argue.

"Have found ter... humans do that often. Usually when defecating," Abathur said. He didn't know camouflage could be so talkative.

Harry, Ron, and Hermione stared at Abathur. Had he said something wrong? Terrans could be so unpredictable. "Abathur," Hermione said. "Sometimes I really wonder about you."

"But ignoring that, Snape has plenty of motive! He worked for You-Know-Who," Ron continued.

"Incorrect. Do not know who. Clarify," Abathur said.

"You know, Voldemort," Harry said, ignoring the others' flinches. "The Dark lord?" Abathur just stared at him blankly. Perhaps he should have investigated the psionics history more.

"How have you never heard of You-Know-Who?" Ron asked.

"Yeah, he's in all of the history books," Hermione said. "You've never read about him?"

"No. Still do not understand relevance. If Snape, servant of Voldemort," Abathur noted the flinches. "Does not give motive to kill Harry." Abathur noted the continued stares.

"Of course it does! Harry was the one who defeated You-Know-Who!" Ron practically shouted. Abathur didn't see why he was being so aggressive.

"When?" Abathur asked. Ron somehow became even redder, a difficult feat considering his hair pigmentation. Abathur was almost impressed.

"When he was a baby!" Ron was no longer employing any method to regulate his volume.

"Unlikely," Abathur stated. "Infants possess minimal brain, muscle development. Incapable of combat. Not possibility."

"Well, that's just how it happened," Hermione said. "All the books say the same thing." Harry himself was quiet throughout much of the exchange. Abathur did not say anything as the argument continued. It took some time to conclude

(Transition)

Abathur was once more wandering the corridors after hours, a task that was much easier with most of the terrans out of the castle for the winter. The biomass refinery required fairly frequent inspections, and the castle still held numerous things to discover, knowledge and essence alike. Recently Abathur had even managed to integrate a particularly interesting creature, an arthropod he had found feeding off psionic energy in an old storage room filled with cauldrons. The ability to digest other forms of energy was always in demand, and this one seemed to be quite versatile. Abathur had killed and preserved a few, for healing, breeding, and experimentation at a later time, consuming the essence of a few more for integration into his own form. It was a complex system, which would take a while, but the ability to absorb psionics, possibly even in spell form if scaled enough would be well worth it.

All in all, it was a very good day, with few surprises and much progress. Abathur was enjoying himself, playing with the new sequences. Then he heard the footsteps. Abathur quickly hid behind a corner, peeking around the edges. He did not want to be caught again, especially when there was more focus on him, simply due to the less numerous students. To his surprise, he saw nothing. If anything, that heightened his suspicions. Terran psionics were infamous for their ability to pass beyond sight. It only made them more deadly. Abathur remained still, listening for any further movement, looking for the telltale shifting of the light. Ghosts were skilled, able to sneak in and out of anywhere. So it was quite a surprise to Abathur when the cloaked terrans revealed themselves through two disembodied pairs of sneakers, walking through the open corridor.

Abathur observed their movements, intrigued. The terrans hadn't seemed to notice him, so Abathur continued to trace them throughout the castle, staying a distance away. As he followed the cloaked beings, he noted the difference between the technological cloaking traditionally used, and whatever the terrans in front of him were using. There was no shimmer, no light emitted, even outside of the terrans visual spectrum, no distortion in the air among. The only way Abathur could follow them was through the noise they made (he could hear many muffled demands for one to move over), and the curiously uncovered sneakers. It was useful, hopefully a spell or biological mechanism that he could claim.

Soon the terrans stopped, turning into a room devoid of anything but a large mirror against the wall. The cloaking device was removed, now appearing to be a piece of fabric, with Ron and Harry revealed underneath. Abathur stood back and observed them. There may be no apparent threat, but that did not mean caution was unnecessary. However, all they seemed to be doing was staring into the mirror, eyes glazed over. Cautiously, he moved behind them, observing their faces, and trying to understand what was occurring. They seemed entranced, staring fixedly at the mirror. In fact, they only noticed Abathur when he was but a couple feet behind them.

"Oh, Abathur. What are you doing here?" Harry asked, surprised.

"Was.. exploring. Encountered Ron and Harry, followed," Abathur answered.

"What? But we were under the..," Harry trailed off, looking at the fabric laying beside him.

"Footwear not covered. Breach in cloak. Sounds, also projected," Abathur supplied. The adolescent terran's face filled with blood, for what purpose, Abathur was unsure. Perhaps it was to look more intimidating? "Your purpose, less certain."

"Oh yeah! You have to see this mirror, Abathur, it's amazing!" Ron exclaimed, tearing his gaze away from said mirror for a moment.

Abathur remained impassive. "Have seen mirrors. Reflects light. Not amazing."

"Yeah, but this mirror is different. It shows you.. look, just look at it!"

Abathur turned to see this apparently remarkable mirror. Then he kept looking. The image within was captivating at first glance. It was amazing and wonderful, magical. IT was everything Abathur had ever wanted, marvelous, unbelievable, and utterly, utterly wrong. Abathur could see it, but he could see so many ways in which it didn't work, so many scenarios where it didn't fit. It tried to change, to reflect the image that Abathur knew to be impossible, but as it had to, given what it was showing, it failed at every step. Abathur got angrier the longer it took, trying to meet his expectations, stealing from his mind and soul every little secret it could to create its mockery. Abathur stood and slowly approached the mirror. He moved forward until he was right in front of it, blocking the view from the others and drawing protests from Ron.

"Hey, mate, you're in the-," Ron was cut off as Abathur drove his fist straight through the mirror.

"What are you doing?" Harry asked, alarmed, as Abathur drew his wand from his robes.

"Wingardium leviosa." Abathur's spell was almost whispered, but the effects were immediate. The defunct mirror was thrust into the air, and as Abathur waved his wand, smashed against every available surface, emitting a loud crash every time. Harry rushed up to Abathur, attempting to get him to stop.

"Abathur calm down! Stop smashing the mirror!" Harry shouted. Abathur turned around, and Harry found his breath trapped in his throat. Abathur's eyes were almost glowing in the low light, a green tinted yellow trapped within his sockets, and all of it was focused on him. But at least something had got through to Abathur. With one last glance at the shattered plane of glass, Abathur ceased the flow of power to his wand, letting the structure crash to the floor. Without another word, he turned and moved to exit the room, leaving the two shocked terrans behind. Right when he was about to reach the doorway, Ron spoke up.

"What... what did you see?" He asked hesitantly, as if afraid of another outburst.

Abathur paused. Then, with a slight turn of his head, he said but one word.

"Perfection."

Overlord: Bulbous, flying creatures, Overlords function as middlemen, spreading and distributing the commands of higher zerg organisms to the soldiers and gatherers of the swarm. Through them, zerg commanders massively increase the number of zerg contained within a brood. Overlords also often function as early game scouts, flying away from the hive cluster and over enemy bases. Overlords are capable of spreading small patches of creep, mostly used to deny the enemy strategic positions, or cover small empty spots in creep carpets. They also function as the zergs transports, morphing large sacs as needed to transport zerg across the battlefield. Overlords morph into Overseers, the detectors of the swarm. While not the most interesting of units, the Overlord is essential to growing and developing hive clusters.
