Due to the steady growth of SCP-6712, More personnel have been stationed to keep civilians away from the area surrounding SCP-6712.

The castle of SCP-6712.
Description: SCP-6712 is a 23 meter long patch of sand where a large city has risen. The border of SCP-6712 forms a circle, and is continuously expanding at a rate of 1.8 meters per month if left undisturbed. SCP-6712 appears to be constructed to match a medieval kingdom, forming a castle in the middle of the city. The castle in the middle of SCP-6712 measures 1.7 meters tall and all surrounding buildings measure at 0.3 meters tall.
There are currently 519 instances of SCP-6712-1 entities inhabiting SCP-6712 and they appear to show no differing features from each other. All instances are completely made of sand, they exhibit no facial features or physical characteristics that would be used to differ instances. SCP-6712-1 entities appear to show very primitive emotions and thoughts, as well as their own language. All SCP-6712-1 instances converse with each other through unknown means, although it is obvious that they are capable of communicating with one another. SCP-6712-1 instances have been noted to rebel against SCP-6712-2 entities that result in mass slaughter, rioting, or pillaging. When SCP-6712-1 and -2 instances expire, the corpses sink into the sand and are presumably utilized to create more buildings.
SCP-6712-2 instances are the "higher class" citizens of SCP-6712, residing in the castle in the center of SCP-6712 and acting as the government/higher class entities. Several riots have been noted between the SCP-6712-1 instances against the SCP-6712-2 entities and on 7/2/2020 the SCP-6712-1 instances seized the castle and the SCP-6712-2 instances were forced into hiding until ██/██/20██ when they overthrew the SCP-6712-1 entities and resumed their hierarchy. While SCP-6712-1 instances have cylindrical heads, SCP-6712-2 entities possess cube-shaped heads.
Addendum-6712.1: In the seven month period that SCP-6712 has been in moderation from the Foundation, SCP-6712-1 and SCP-6712-2 have caused ████ deaths due to but not limited to: civil wars, riots, and murder. SCP-6712 instances typically use spears, swords, pitchforks, or knives.
Addendum-6712-2: In the event of a "Natural disaster" typically referring to a strong tide washing up onto the city, SCP-6712 instances will expire instantly if they come into contact with a heavy tide, and/or washed out to see and expiration occurs within the next minute. ████ deaths have been caused due to natural disasters.
