The '3' must be relation to 'a' glyph (if indeed thats what Chelsea is talking about). We know that a solution or a key from one doesn't effect another. So it could be, that there are three parts to find in each glyph. ...But that just makes more numbers to find ...and my head really doesn't like the sound of that, I'm having a problems finding one, let alone three;/

"Seven steps down, in a building, I found three rooms. Each room contained a special key to a special lock."

A special key to a special lock
