The entrance to the Stone Portal is initially blocked by a Galaxy Team member. The player is allowed access into the area during Mission 17: "Atop Mount Coronet", where they must pass through to confront Commander Kamado at the space-time rift. Upon their first arrival, the player's path is obstructed by Beni, much to the player's surprise. Beni challenges the player to battle by word of Kamado. After being defeated, Beni acknowledges his respect for the player's skills, and allows them passage.
Geography
Wall etchings depicting Legendary Pokémon
The Stone Portal is a path that acts as the final checkpoint that connects to the Temple of Sinnoh. It has two sets of slopes, with a flat area between the two. There is an ancient drawing inside the cave, depicting multiple Legendary Pokémon. These are similar to those found in Tidal Passage.
Shop
During Mission 18: "The Counterpart", Volo can be found here as a temporary shopkeeper before the player confronts Dialga or Palkia. Volo cannot be found here to sell items again after completing the mission.
