Mt. Battle: The climb toward darkness
You meet an acquaintance from Gateon Port, then head toward the entrance. Take the Full Heal on the way, to the right of the entrance door.
Inside, talk to the receptionist, who offers to let you in to talk to the Area 1 leader.
You enter Mt. Battle, then battle two young Trainers before meeting the Area 1 leader, who suggests you beat a third young one for the road.
Once that is done, you go back to the reception, and he advises you to go to a Mysterious Building resembling a Research Center to the south, in the desert.
Head there.
