Cliff Edge Gate

Cliff Edge Gate connects Cianwood City to route 47. It is a small cave with a counter with a lady behind it, and a map of some sort. Once you've gotten the red or blue orb (depending on the game) from mr. pokemon after you've beaten red and got your Kanto starter and you come here going to the embedded tower, than you will see Chuck and he will tell you something, then run off.
