randlocs fire red

/scav queue aQrator | I've been giving my totally legal Fire Red a try, but after trying to enter the Viridian City Pokémon Center, I ended up in a museum? It looks like every entrance leads me somewhere random. Want to help find me where I am? Give the name of the location. The floor does not have to be defined. First up, I exit through a ... closed door. There seem to be 18 dots on the door, some black and some white. Where am I? | Ruin Valley | There's a hole in the wall, and a lot of footprints on the ground. The people inside appear distraught. I mean, I get it, someone just appeared out of nowhere, but they said someone stole something from them. Where am I? | Cerulean City | It took some time but I finally beat Bruno. In trying to move on to Agatha, I am relocated to the entrance of a cave. There's no items, no other exits or stairs, only two species of Pokémon, some sand or something on the left, and a tiny set of stairs on the right leading to a plateau. It feels like I've been here before in another life, or dimension, or something... Where am I? | Altering Cave
