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]].

==Geography==

The Crystal Pool is a large 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 {{p|Terapagos}}, suggesting the Pokémon and the area itself may be related. 

Sparkling [[Crystal Cluster]]s can be found within the pool, with the player receiving one after being attacked by a {{p|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.

===Bringing Terapagos===
{{spoilers}}
Following the events of [[The Indigo Disk]], a strange mist will appear at the Crystal Pool provided the player returns there. The player, as well as [[Koraidon (game)|Koraidon]]{{sup/9|S}}/[[Miraidon (game)|Miraidon]]{{sup/9|V}} is then able to meet the real Professor Sada{{sup/9|S}}/Turo{{sup/9|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{{sup/9|S}}/Violet{{sup/9|V}} Book. The player cannot deny the request made by Sada{{sup/9|S}}/Turo{{sup/9|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 [[Area Zero journals|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{{sup/9|S}}/Miraidon{{sup/9|V}} their name yet at this point in their life, (referring to them as the {{p|Koraidon|Winged King}}{{sup/9|S}}/{{p|Miraidon|Iron Serpent}}{{sup/9|V}}) it is implied that this encounter inadvertently triggered a {{wp|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 [[Bond|close bonds]] with him) reveals different dialogue about the location of the book as a result of this interaction.

==Special encounters==
After [[Carmine]]'s grandpa offers to fix {{ga|Ogerpon}}'s mask, the player and Carmine head to the Crystal Pool to obtain a [[Crystal Cluster]], where a {{p|Milotic}} ambushes them. Milotic's stats are different if the player has not yet finished {{DL|Pokémon Scarlet and Violet|The Way Home}}, but it always has 20 {{IV}}s in each stat. It cannot be caught, and is coded to never be {{Shiny}}.

After it is defeated, it drops a Crystal Cluster.

==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's never shown to the player in-game, the special Milotic encounter is programmed to have a {{t|Ghost}} Tera Type, which may imply that the rumor about seeing the deceased at the Crystal Pool (as mentioned by Carmine) is true.
