Item #: SCP-6520
Object Class: Keter
Special Containment Procedures: an SCP-6520 pack is to be kept in a 25 by 25 meter containment cell to fit all instances and must be under 24-hour surveillance by 10 or more armed guards and sedated using sleeping gas at all times to ensure that no containment breach occurs at the site that SCP-6520 is being held at.
Description: SCP-6520 also known as "The pack of the blind" to foundation personnel are canine quadruped entities resembling a wolf that hunts in packs of 10-20 instances with one instance which is considered the Alpha of the pack by the other instances.
SCP-6520 has pitch black fur, luminescent white-colored eyes, very sharp claws, and it seems like all of its frontal teeth have been replaced by canines, various tests have also shown that SCP-6520 has an intelligence level that is on par with humans yet it doesn't use oral speech for communication.
Instead, it uses telepathy or howls to communicate with its fellow instances and uses affection to life forms that it doesn't see as food which includes some foundation personnel but shows signs of aggression towards most personnel which led to it being put in Keter class.
Discovery: SCP-6520 was originally found by Dr. Dimitri that was on hiking in Mt. Everest, he said that while he was hiking he saw some animals which looked like a pack of wolves, he thought that it was strange that there were wolves that were living in very high altitudes so he called the foundation and told them all the details of SCP-6520 that he could see.
The pack of SCP-6520 containing 13 instances that Dr. Dimitri informed the foundation about was soon sedated using sleeping gas and was all put in a 25 by 25 meter containment cell with a vault door, no sedatives, and 20 cameras observing the pack, at first SCP-6520 didn't cause any commotion but after all of the SCP-6520 instances woke up, the Alpha of the group howled and all instances stood still for a couple of minutes.
After standing still for a few minutes, the whole pack started to position themselves like they were preparing to attack, the Alpha growled and all of SCP-6520 started to maul the door which led to the destruction of the door, luckily the foundation had set up a trap outside the containment cell which releases sleeping gas once any part of the containment cell was damaged, which led to sleeping gas being put inside the containment cell and 10 or more armed guards as a safety precaution.
