Ok so where do I go from here?
I got all Kanto Badges, I dismembered Team Saturn in the hidden cave of Cinnabar, then talked to Oak, got access to Mt.Silver, where there are only 3 gentlemen instead of Red.
I tried the Orange Islands gate but the guard says it's not stamped. I tried the Undersea cave, where I found a Ruby and a Meteorite, and a place in the middle of a current tthat lead me to Dragon's Den, with a cave entrance next to it, that contained an infinite stairway
What am I supposed to do now?
