Elm

You've been hired as a worker at KONTUR to study anomalies and take samples. The work is dangerous, but well-paid, and if anything happens, no one will be held responsible. Safety rules for contact with creatures, including one called Vyaz: Do not approach the creature while it is actively moving between buildings.
Hide under a car or other dense cover and remain motionless until Vyaz freezes or leaves the perimeter.
If you leave the house where the Elm is located, return immediately and do not leave until the entity moves to another building.
If you're already deep inside the Facility, return the way you came. Any deviation from the path increases the risk of entering more unstable areas of the simulation.
Don't try to harm the entity. Even if you manage to damage it, the Tentacles will disintegrate into smaller ones and drag you deeper into the Facility.
In wooded areas, Tentacles can camouflage themselves as tree trunks. If you spot a "breathing" tree trunk, immediately lie down on the ground and freeze.
You emerged from it alone, you were used as a template to lure Vyaz into a trap. A huge creature loomed among the quarters, madly.

The elm appears as a massive structure with long organic tentacles that can reach 50–90 meters in length. These are presumably living energy storage facilities for the O-41 fungus, which it uses to fuel the simulation.
Behavioral and lifestyle characteristics:
Most often, the Elm is fixed on the borders of infected Objects and moves mainly along their perimeter.
Most of the time the creature is in a passive state, but approximately once every few hours it switches to a phase of active movement.
Upon detecting a human, Elm begins a slow and continuous pursuit, perceiving the human as a source of energy.
Individual tentacles can extend deep underground or high into the sky, presumably connecting with the Mycelium—another element of the K.O.N.T.U.R. universe.
Why is it dangerous to come into contact with her?
Any attempt to approach or touch the Elm provokes an aggressive reaction. However, it is impossible to destroy it: during the organization's tests (for example, as part of the "Liquidation" test), it was discovered that when damaged, the Tentacles disintegrate into smaller, autonomous parts and disperse throughout the Facility.
Rules of Survival
The training materials for K.O.N.T.U.R. employees provide the following recommendations when meeting with Vyaz:
Do not approach the creature while it is actively moving between buildings.
Hide under a car or other dense cover and remain motionless until Vyaz freezes or leaves the perimeter.
If you leave the house where the Elm is located, return immediately and do not leave until the entity moves to another building.
If you're already deep inside the Facility, return the way you came. Any deviation from the path increases the risk of entering more unstable areas of the simulation.
Do not try to harm the entity.
