Pokémon Diamond and Pearl/Oreburgh Gate

Events

 * Almost immediately, a hiker will walk down and give you HM6, Rock Smash. This HM is not currently usable outside of battle, but that will be resolved after you beat Roark. To get to Oreburgh, just go to the right, passing behind the trainers' backs if you like.

Floor 1

 * There is a hiker who will give you HM 6 just to the right of the left entrance.
 * There are two trainers to the left of the right entrance, although you may step behind their backs to avoid battles.
 * To the north, there is a small passageway blocked by rocks. These can be Rock Smashed to reach the lower level.

Floor 2

 * There is a biker that explains that the jumps can be only made with a bike.
 * There are some items (need exact items and locations)
 * There is a Veteran and a couple of items accesible only after Surf and the neccisary badge are obtained.
