You can visit any supermarket or a bookshop to get the permanent marker of walls.
I had permanent marker all over my wall once. I used the Mr. Clean Magic Eraser and it worked amazingly. There is no trace of permanent marker on my walls at all. And it doesn't matter how long the marker has been on the walls for, because i waited 7 months before even trying to remove it. They are not expensive and they defiantly do the trick.
It's a 'boundary marker' - just as humans build walls around their land to keep others out !
