Hall of Origin

The Hall of Origin (Japanese: はじまりの Hall of Origin) is an area where the Mythical Pokémon resides.
The area originally appeared in , but is only legitimately accessible in the remakes, Pokémon Brilliant Diamond and Shining Pearl. It is located above the Spear Pillar, and can be reached after entering the Hall of Fame and obtaining the National Pokédex by returning to the Spear Pillar with the Azure Flute. In Generation IV, the Azure Flute was an event item that was never distributed, but it can be obtained through regular gameplay in Generation VIII.
In Pokémon Legends: Arceus, the Hall of Origin is not labeled as such in-game, and is instead treated as part of the Temple of Sinnoh. The soundtrack does refer to it as the Hall of Origin.
==In the core series games==
===Generation IV===
In , when the player returns to the Spear Pillar with the Azure Flute, they will be asked to blow into it every time they step one tile north from the entrance until they catch Arceus. Upon doing so, a glowing staircase will appear, leading to an elevated glass platform high above the Spear Pillar, where Arceus awaits the player's challenge. The camera will also broadly overhead and zoom out, giving the player a unique view of the area below as they ascend the staircase. Stepping onto the edge of the glass platform will automatically initiate the encounter sequence and . Should Arceus be defeated rather than caught, it will "disappear from sight" but the Azure Flute can be reused to summon it again.
In terms of game mechanics, when the player accesses the Hall of Origin by blowing the Azure Flute, they are actually no longer on the Spear Pillar but rather in a completely separate location, as evidenced by the screen fade-out transition and the change in location header. That is, the game does not place stair tiles onto the Spear Pillar map, but rather warps the player to a new map containing the stairs where the surrounding area looks identical to the Spear Pillar, exactly down to the cave opening that still leads into the mountain interior. This dispels a rumor that cheating to reach the Hall of Origin would trap the player on the elevated glass platform without the stairs to lead back down.
Like the Spear Pillar, the Hall of Origin is an internal area separate from Mount Coronet, so the Escape Rope as well as cannot be used to leave the location. However, like the Spear Pillar, it is within the range of Mount Coronet's special magnetic field and so and will both evolve here if leveled up.
===Generation VIII===
In Pokémon Brilliant Diamond and Shining Pearl, the location can be visited legitimately. To obtain the Azure Flute, the player must possess Pokémon Legends: Arceus save data with all the completed, update the game to Version 1.3.0 or later, and be registered into the Hall of Fame. Once these conditions have been fulfilled, the Azure Flute will appear in the player's room in Twinleaf Town. After the player catches Dialga or Palkia, and also obtains the National Pokédex, they can play the flute at the Spear Pillar to access the Hall of Origin.
In Pokémon Legends: Arceus, after defeating Volo and in Mission 26: "Seeking the Remaining Plates", the player will obtain the final Plate as well as the Azure Flute. The player then has the opportunity to play the Azure Flute on the Temple of Sinnoh's dais at any time. However, the stairs to the Hall of Origin will not appear until the player has caught every non-Mythical Pokémon in Hisui. The player will also receive a message from on the Arc Phone if they attempt to do so, repeating the message, "Seek out all Pokémon."
Once the player has caught all non-Mythical Pokémon in Hisui, playing the flute will cause a glowing stairway to appear on the north side of the temple, which the player will automatically climb. After climbing the stairs, the player will find themselves in the Hall of Origin, which has a completely different design than in Generation IV. Arceus will appear behind the player, transform their Arc Phone into Mysterious Balms, and immediately challenge them to battle. The player can revisit the Hall of Origin at any point through Temple of Sinnoh to have a rematch with Arceus, and can also visit it for Arceus's Eternal Battle Reverie challenge by going to sleep at Jubilife Village.

Although not by name, the Hall of Origin was mentioned by Archer in With a Little Help From Hitmonchan. When appeared in front of the four s and on , Archer explained that Team Rocket had first found and awakened the Alpha Pokémon "in a far-off land at the end of a long road, which seemed to continue on and on up into the heavens," obviously describing the Hall of Origin. He also revealed that Arceus had come to Johto due to all of its Plates being currently located in said region.
==Trivia==
* Two versions of the Hall of Origin map exist in : one is the real location while the other is a "fake" copy. The "fake" Hall of Origin uses Spear Pillar as its theme and can be accessed through the void glitch using "Stickyman's Spear Pillar Hall of Origin" method,Void Knowledge Archive, by the members of HallofOrigin - Google Drive named after its discoverer. The "fake" Hall of Origin contains no warps or events and no . (YouTube video)
* Unlike and , simply obtaining access to the (real) Hall of Origin (e.g. through the void glitch) does not mean that the player can battle there. This is because the scripts in the area are normally programmed to only trigger through the Azure Flute script in the Spear Pillar. The player can ascend the stairs, but the script to uniquely tilt and zoom the camera will not activate, nor will the script to have Arceus challenge the player when they step onto the glass platform. The Arceus sprite still appears, but just as in the actual event, it cannot be directly interacted with. Additionally in , as with Darkrai and Shaymin, the Arceus sprite will not appear in the area at all unless the player has the Azure Flute in the Bag. To actually battle Arceus in the Hall of Origin, the challenge script itself must be triggered (see Pal Park Retire trick).
* In Pokémon Legends: Arceus, the Hall of Origin resembles the pattern seen during the Sinjoh Ruins event in .
