The Crystal Pool (Japanese: てらす池 Illuminating Pool) is a large pool located at Oni Mountain summit in the center of Kitakami. It is one of the Six Wonders of Kitakami.

Origin

The Crystal Pool of Kitakami directly reflects the Terastal phenomenon found in Paldea. Its plaque notes it was "infused with crystalline material from an unknown source." Briar's research reveals that "the Crystal Pool's waters emit energy of the same wavelength as Terastal energy."

Kitakami folklore about Ogerpon deepens this connection. A man journeyed to Kitakami from a distant land alongside Ogerpon and brought with him gems from somewhere far away. Because their appearance was considered unusual for the standards of Kitakami, they lived apart from the village, settling in a den inside Oni Mountain, the very mountain where the Crystal Pool is located. The village mask-maker then crafted four masks using these gems, enabling the pair to blend in during the village festival. This origin implies that the Terastal crystals found their way to Kitakami through human agency. Moreover, the presence of Glimmora, a species otherwise exclusive to Area Zero, at the Crystal Pool reinforces its role as a mini–Area Zero.

In conclusion, the most likely origin of the Crystal Pool lies in the arrival of foreign gems, arguably Terastal crystals from Paldea. Brought to Kitakami in ancient times and infused into the pool, they seeded the waters with Terastal energy, transforming it into a secondary hotspot that mirrors the properties of Paldea's Area Zero.

Geography

The Crystal Pool is an area at the top of Oni Mountain. A small, man-made bridge has been built around a longer strip of water. Glowing crystals, like the ones found in Area Zero can be found at the bottom of the pool, rising upwards to the surface. When travelling there with Carmine, during the events of The Teal Mask, she mentions a rumor about the Crystal Pool where you can happen to meet people here who have passed away. Briar refers to the area as "sacred ground" upon her arrival. According to her, the crystals emit energy of the same wavelength as Terastal energy. She doesn't understand why this is the case, but hopes to figure that out to stabilize the Terastal phenomenon in regions other than Paldea. After Carmine leaves, Briar also mentions that her research here could bring her one step closer to Terapagos, suggesting the Pokémon and the area itself may be related.

Sparkling Crystal Clusters can be found within the pool, with the player receiving one after being attacked by a Milotic during the events of The Teal Mask.

Places of interest

Lake caves

On the far side of the area, there's a small hole beneath the ground that the player can enter. It will take them to an underground lake beneath the river, where Pokémon such as Feebas may spawn.

Post DLC

Spoiler warning: this article may contain major plot or ending details.

Following the events of The Indigo Disk, a strange mist will appear at the Crystal Pool when the player returns there. The player must have Terapagos either in their party or Pokémon Storage System for the cutscene to activate. The player, as well as Koraidon^S/Miraidon^V, is then able to meet the real Professor Sada^S/Turo^V from some point in space-time, who has not yet completed their time machine. After a brief conversation implying that Paradox Pokémon come from parallel timelines, the player will be prompted to exchange Briar's Book for the Scarlet^S/Violet^V Book. The player cannot deny the request made by Sada^S/Turo^V to trade books. Following this scene, the player will be returned to a permanently different main menu, where the Book will be visible again, featuring a new arrangement of the main Pokémon theme.

Even before this point, the player is able to read the Professor's notes in the Area Zero Underdepths, noting that they received a white book from a child in an eastern land. Since the Professor doesn't seem to have given Koraidon^S/Miraidon^V their name yet at this point in their life, (referring to them as the Winged King^S/Iron Serpent^V) it is implied that this encounter inadvertently triggered a bootstrap paradox by telling them what their Legendary Pokémon was called and inspiring the Professor to continue their research on Area Zero or possibly creating an AI, if the player references it in their dialogue.

Talking to Arven in his dorm at the Academy (provided the player has formed close bonds with him) reveals different dialogue about the location of the book as a result of this interaction.

Special encounters

After Kieran and Carmine's grandpa offers to fix Ogerpon's mask, the player and Carmine head to the Crystal Pool to obtain a Crystal Cluster, where a Milotic ambushes them. Milotic's stats are different if the player has not yet finished The Way Home, but it always has 20 IVs in each stat. It cannot be caught, and is coded to never be Shiny.

After it is defeated, it drops a Crystal Cluster.

Pokémon Horizons: The Series

The Crystal Pool was first mentioned in Roy is Crocalor, and Crocalor is Roy!, where Carmine revealed that Briar was currently there. In Encounters at the Crystal Pool, Liko, Roy, Dot, and Friede arrived there and met Briar following a brief battle against a Terastallized Milotic. The Rising Volt Tacklers members subsequently shared with Briar what they knew about Terapagos, and Briar, in return, shared with them the story of her ancestor, Heath, and her research into Terapagos. After nightfall, they visited the shore of the Crystal Pool in the hopes that the legend about the place allowing one to meet those who have died was true and they'd be able to meet Lucius. However, nothing happened, so the group left Briar's camp the next morning.

In The Three Explorers, Liko, Roy, Dot, and Friede returned to the Crystal Pool alongside Diana, hoping to learn more about one of Lucius's fellow adventurers, Rystal. This time, the pond's rumored power worked and brought Rystal in front of them, along with her baby. From her they learned that Terapagos had originally been her partner Pokémon. When she referred to her baby as Layla, Dianne identified it as the name of her mother. Rystal then revealed that Layla was the daughter of her and Lucius, meaning that Liko was Lucius's direct descendant, much to her shock. In the following episode, Rystal told everyone how the original Explorers, which consisted of her, Lucius, and Gibeon, had discovered the Laqua paradise and what they had experienced there. Just before she and Layla disappeared back into the past, Rystal told Liko to take care of Terapagos. As such, Terapagos subsequently requested to be caught by Liko, which she happily agreed to.

Trivia

• The overall layout of the Crystal Pool resembles a smaller version of Area Zero, with the location resembling a crater surrounded by a ring of jagged mountain-like rocks, akin to the Great Crater of Paldea, and containing a lower subsurface area in the center filled with crystals, similar to Area Zero's depths.
• Although it is never shown to the player in-game, the Milotic in Crystal Pool's special encounter is programmed to have a Ghost Tera Type, which may be a reference to the fact that the Crystal Pool can allow one to meet the dead.
  • Incidentally, in Pokémon Horizons: The Series, the Milotic that appears out of the Crystal Pool does Terastallize into a Ghost Tera Type.
