The place to exit and entrance the Ministry of Magic, you go to the fire place, grab a handfull of soot and say where you're going nice and clearly. Green fire will erupt around you and then you'll be gone.
When you arrive here you make a soft shft sound and green light surrounds you for a moment, but it doesn't matter. It's time for you to start your job!

This place is a long corridor covered with green tiles and rows of fire places, around 10 on each side. The hall is generally very busy and if you don't have a pass on then you're probably going to be stopped by someone, so don't forget it!
