 This is by far the most powerful backroom's object that you could use, and if you find it, well. Good luck! It's called the Hermes device, named after the Greek god Hermes, obviously. Anyways, this object gives anyone holding it the ability to travel across levels in the backrooms at will. The object itself looks like a human brain floating in some kind of liquid, and specifically the liquid is thought to be a potent mixture of memory juice and a level key somehow. The main theory on how this works is that when you touch this object, it induces dreaming for the person holding it. And when you dream, you dream about a specific level, and then you'll be sent to it somehow it knows. Some of the devices can take you across hundreds of levels, and some can only take you across 10 or 20. All we know is that these things are really hush-hush, and very few people know how to make them. What are your thoughts on them? Let me know in the comments.
