On the origin of vaal and miscreation

I am an exile, I drifted to an island. The people over there accepted me as their inhabitant. I was very curious about the buildings on the island, so I asked the master about the source of their building. According to the literature, in the ancient times,the residents saw them descending from the sky, wearing huge and huge armor, driving huge humanoid objects to mine. When a huge moving box is deformed, it will emit a thunder that shakes the earth. Any object will be destroyed in the direction of the box. They helped the residents to kill a lot of life-threatening monsters. Many of the basilisks and the snakes that pierced the earth were killed one by one. They once knocked down a huge beast flying in the sky.
The house at the entrance to the island is said to have had a name called a bunker. There are two-finger-shaped box objects, and the gears next to them have never stopped moving. I heard that there is a function of destroying the ground. The strange box-shaped houses on the high ground have mysterious power, which makes the surrounding objects have an endless source of energy. They used to come from heaven and told the residents here that they rely on this huge box to provide energy and deliver substances. I am very surprised, how does the box convey material? The giant who stopped mining still holds the materials. Huge circular buildings, the lights are not extinguished and occasionally strange sounds.
People began to create a village around them. Lived till now. In addition, it is said that in 1330, a visitor named malachai stole a part of the instrument, and nine years later a beam of light was shot from the burial place of a huge monster. The earth is really shaking, and many people are afraid to leave here. From that day on, the residents saw it again, punctuating the earth's basilisk.
I saw a lot of vaal text on the walls of these buildings, and I also saw a lot of map device symbols. Is this town the origin of vaal?
