Spawning in the world, you stand in front of the entrance to his secret Lair, aswell as a test machine at your left that I left behind so players can examine the basics of how the elevator works. 
Pressing the button to make the elevator go down, you slowly descend and witness just how huge his Lair is compared to everyone else's in the server. (Be aware that the elevator only goes down up or down, you can't call it to go down when it's up) 
The first thing you may notice is the huge portraits of discs on the wall aswell as a nether portal in between. This is where dream keeps Tommyinnit's most prized possessions. 
In the hall, is where dream locks and keeps everyone's most valued attachment to the server, such as weapons, items and pets to keep Dream on the top with power over everyone. These items have valued attachment by the players which is why dream wants to take all of it.
