Damn swamp

There are a lot of places in Udmurtia where abnormal and strange phenomena occur. Most anomalies are observed near the Kama River. One of these places is the "Devil's Swamp".

This place is quite strange: the tops of the trees seem to have been cut down, there are no branches at all.
Locals say that there used to be a large village on the site of the swamp. But one night this village disappeared without a trace, and a swamp appeared in its place. Near the swamp, relatives of the residents of the missing village have repeatedly arranged searches, but they have not found anything. Some residents claim that the voices of people, mostly women, are often heard above the swamp.

Passing by the swamp, many have an inexplicable feeling of panic, and sometimes terrible fear. Also, huge glowing balls are constantly visible above the swamps. The shape of the swamp is a triangle.
