From the outside, it looks to be just an average bridge. Connecting one building to another through the form of a walkway. But really it’s the passageway from the mutant world and the human world. No ordinary person can just cross this bridge. Let alone even find it. Yes from down on the street, it is visible. But once you get up there, it’s no where to be found. The passage way is hidden behind a brick wall. And there are three things a mutant must do in order to unlock the passageway. First you must say the word MUTALIS. Then you must trace your finger down the white lines in between the bricks. There is a certain row you must trace. And lastly you breathe a puff of air onto the brick. Mutants have a specific chemical compound that lingers in their breathe and blood; and the brick was designed to decipher that. After you complete those three steps, the brick wall then pushes itself back and splits in half. Revealing this walkway to the other side.
