"'Arvent.' 'Meren.' Those are names that they gave our two most esteemed. Whether they knew that is irrelevant, because that is simply what it is."

"When a single person alone could shatter mountains with the lift of a finger, and survive the falling of the sky, what happens when there are millions or more of them in a mountain-sized realm under the same sky?"

The City of the Shining. Cyri. The City of Lights. Arvendalin. Ylir. Anyone who's been up north has heard of it somehow. That hidden city, in the northernmost frigid wastes of the world.

Ylir is a place inhabited by the powerful 'Slachi' people, who have isolated themselves from the rest of the world and at the same time gained extreme technological prowess through their own self-driven advancement. Ylir is a community. It is a location. But it is also a state of being. One cannot find Ylir simply by walking to the north pole. Rather, it is hidden by a cloak of false reality - further frozen waste. But behind that is, of course, the City itself. Entering it, you would immediately find the very air saturated with a strange power, a manifestation of the extreme power the City, its inhabitants, and its technology have. And once past all the struggles that the people of the world face, they turn to art, expression, and performance. And their performances are extreme. A cacophony of powerful influences rocks the City to its core every second, enough that an unfortunate foreigner might simply be swept up into some mysterious fate. But those of the City enjoy and engage in it, simply because they can.
