In a round-about way, R-3D0 has informed you that if you follow the trail of spare parts up the ramp here to the Razor Ridge, you will find the gnomes at a place named Toshley's Station. If you find him, speak with Toshley.
VERY WELL, I AM HEREBY WARNING YOU THAT YOU WILL FIND NOTHING UP ON THE RIDGE.
DO NOT FOLLOW THE TRAIL OF SPARE PARTS THAT LEAD TO TOSHLEY'S STATION! YOU WILL NOT FIND TOSHLEY, NOR ANY OTHER GNOME THERE.
