From Bulbapedia, the community-driven Pokémon encyclopedia.
The Embedded Tower (Japanese: うずもれのとう Hidden Tower) is an area located on Route 47 in Pokémon HeartGold and SoulSilver. It is where GroudonSS/KyogreHG and Rayquaza rest.
KyogreHG/GroudonSS appear at the Embedded Tower when the player is in possession of the Blue OrbHG/Red OrbSS (which can be received from Mr. Pokémon after the player has obtained a Kanto starter Pokémon in Pallet Town after defeating Red). If a Kyogre and a Groudon that are caught at the Embedded Tower are both shown to Professor Oak, he will award the player with the Jade Orb, which causes Rayquaza to appear at the Embedded Tower; Professor Oak will not give the Jade Orb if shown Groudon and Kyogre from any other location.
The appearance of the interior changes depending on which of the trio occupies it at the time. If Kyogre is in the room, the markings on the floor will be red and depict the pattern on Kyogre's fins. If Groudon is there, then the markings will be blue and show Groudon's arm patterns. If Rayquaza is occupying the Embedded Tower, then the markings will be yellow and represent those on Rayquaza's body.
A long time before the events of HeartGold and SoulSilver, the Embedded Tower was an enormously tall tower built by people who came from the Hoenn region. Its peak was said to touch the sky, and part of it was embedded into the cliffs of Route 47, running deep underground into the ocean— thus connecting the land, the sea, and the sky.
A KyogreHG/GroudonSS will appear here if the Blue OrbHG/Red OrbSS is in the bag. If defeated or run from, it respawns after entering the Hall of Fame.
A Rayquaza will appear here if the Jade Orb is in the bag. If defeated or run from, it respawns after entering the Hall of Fame.
In the manga
In PS611, the Embedded Tower was revealed to be the place where the Pokémon Association had found and captured Rayquaza years earlier. This operation had unintentionally also led to the death of Aster, a Draconid lorekeeper, who had tried to defend Rayquaza from being captured by Mega Evolving it. As a result of Aster's death, her successor, Zinnia, had sworn a vendetta against the Devon Corporation, which had participated in the capture operation.
- If the Blue OrbSS or the Red OrbHG is obtained with an external device and brought to the tower, the appropriate etchings will appear on the floor. The Pokémon itself will not appear, however.
