SCP-173/Koitern
A very bad man in the previous iteration. He is both dangerous, a savage dictator, and a madman. Singlehandedly waged genocide on about 1/3 of 682's countrymen in the past iteration.

Beware the Koitern, o' my child, In cities tall and forests wild, Beware the stench of death he makes, Lest it be your neck he breaks
Incident 682/053/1129/173:
[00:00]: Visual distortion appears in the corner of SCP-173's cell. SCP-173 ceases movement between individual frames .
[00:57]: Visual distortion resolves into spatial distortion and suspended biological mater consistent with SCP-1129.
[01:22]: SCP-053 emerges from the spatial distortion, riding on the back of SCP-682. Both entities appear to be in a joyous mood.
[01:27]: Both entities cease movement and fixate their eyes on SCP-173.
[01:49]: SCP-682 begins to grow transparently-armored eyes covering various points of its body.
[02:36]: SCP-682 charges through SCP-173's cell wall.
"Don't take your eyes off of him!" Atanti charged through wall after wall, the rubble occasionally granting the Koitern enough cover to catch up to them.
"I'm not!" Guards opened fire at random, trying to hit both the travelers and each other.
"Edrisek! Look before you take us to someone next time!" And with a swirl and a flash, our travelers disappeared.
Beware the Koitern, o' my child, In cities tall and forests wild, Beware the stench of death he makes, Lest it be your neck he-

"Atanti's thoughts drifted to his homeland. Now that it was the warm season, the land and people would be brimming with life. Grasses would be springing up everywhere for picking and crafting. Swarms of Snaes would be ticking through the air as children attempted to catch them. Great feasts would be held by his family in the fields and meadows.
At least, that would have been what he was thinking about, if he wasn't running for his life through the underbrush. It had been poor luck indeed, running into the Koitern's men on a simple expedition. Thankfully, they were only explorers themselves, meaning that the Koitern was likely still worlds away and that Atanti still had a chance of survival. Still, even the explorers were ruthless and bloodthirsty, not to mention that they outnumbered Atanti eight to one.
Atanti ducked into one of the more familiar tunnels he was exploring, and, after several more minutes of running, managed to shake off his pursuers. They had originally been riding north-east at a rapid pace, meaning that they were most likely only scouting, and had only stumbled on him and this site by accident. By that logic, they would most likely be gone in a few hours.
Rather than simply lie down and wait out the rest of the time, Atanti chose to use his head-start into the cave to explore further, then return to his encampment as the suns began to set. After a few more hours of traversing the tunnels and caverns, the sparse rooms and architecture grew more and more frequent, until Atanti found himself inside a large and well decorated room.
Atanti reviewed the knowledge he had of the caverns and tunnels. They were most likely built by the Oom peoples millenia back. The towering idol at the far end of the cavern matched the image of Sutkak, a large, green trident covered in straight, pointed horns. The Oom believed that Sutkak would be the one god to survive the end of the world. They also, strangely enough, believed that he was the god of music. Given the giant icon of Sutkak, and the structure of the room, Atanti reached the conclusion that this was the rumored Grand Chamber of Sutkak. The Oom had believed that this chamber was the ark that would carry them through catastrophe. They believed that it would allow them to survive the end of the world, that it would make them immortal.
While reveling in the beauty of the room, Atanti couldn't help but think of the prestige that his discovery would bring to the ql-Paneus, or even the Paneus in general. These thoughts of grandeur were rudely interrupted by a resounding "CLANG!" The doors of the chamber had shut behind him. It was impossible. Atanti has checked the room for traps as soon as he had entered. There was no reason that the door should have closed, unless…
Panic rose in Atanti's hearts as ancient singing began to emanate from the statue at the end of the room. His thoughts turned to his wife and children, brothers and sisters. He had to get to them, had to save them. When the storm struck the ark, hairline fractures began to appear in reality, but it did not break. The ark held. The resolve holding back Atanti's tears did not.
...
The Koitern stared out past the horizon. The mighty Koitern, feared by all, slaughterer of a tenth of the world. The Koitern, with his heart of stone. He watched as the empire he had created ceased to exist. He watched as the oncoming storm approached his throne room, filled with the blood and filth of all those he had executed with his own hands.
There was a legend about the Koitern. It was said that he would not kill you so long as you met his gaze. That some force of mutual defiance stayed the hand of death. Most disregarded the legend. Few tried it, and they found it to be true. Unfortunately, no one could meet his eyes forever. What no one knew was that the reverse of this effect was also true; the Koitern would not kill any who met his gaze, but none whose gaze he met could kill him.
And so, the Koitern looked the end of the world in the eyes."
