==History==
===Pre-series===
100 years prior to the events of the series, a Pokémon paradise known Laqua was found by the original Explorers, Lucius, Rystal, and Gibeon. Wondering how such a prosperous environment could exist, they explored further in and discovered a large chunk of pink crystals known as Laquium, which were stimulating the growth of the plants around it, so much actually that it started devastating the land. Worried how the crystals could affect them, Lucius suggested that they should leave Laqua. 
Fascinated by the energy the Laquium possessed, Gibeon ignored Lucius's warning and used his to begin digging the crystal out. This caused the Laquium to expand and release a pink mist around the area, forcing many wild Pokémon to go feral. Fearing the could be destroyed, Lucius called on his Six Heroes to try and stop the Laquium. Gibeon's Zygarde attempted to help by covering the crystals with its Cells, only for them to be blown away. The expansion created a hole in the ground below Gibeon, who promptly fell inside, much to his friends's horror. Despite this, Lucius and Rystal refused to back down. Motivated, Rystal's , Pagogo, changed into its and bestowed some of its energy to the Six Heroes, so all of them could seal the Laquium away. Lucius remained trapped inside it and told Rystal to escape and protect their still unborn child.
After Gibeon survived the fall thanks to the power of the Laquium shard he had with him, he escaped Laqua with the shard, founded the Exceed company in Paldea to research on it, and used its mist to expand his lifespan as long as possible so he can lead the newly reformed Explorers.
======
The Laquium was first mentioned by Gibeon in From So Far Away within his chamber while musing about his desire to reach Laqua, obtain the Laquium, and claiming that Lucius's adventure wasn't over yet.
In The Treasure of Eternity, it was revealed that at some point, Exceed discovered the Laquium somewhere and took it to the company building to research it, naming it the "Treasure of Eternity". However, nothing came of it, until eventually they gave up on it, storing it deep within the labs.
After Friede confirmed the appearance of a pink mist every time a vision of Lucius is created by , he decided to return to Exceed, where he once worked for as a scientist, seeking for more information about Terapagos and Laqua and specially their connection to a mysterious material he knew about before leaving the company. After going into the lower labs and fighting off some Pokémon that were guarding it, Friede found out that the Laquium had been stolen, with the culprit being secretly revealed to be Spinel.
In Roy and Fuecoco's First Snow!, Raifort claimed that Laqua possesses a pink shine, which confirmed to Friede that the Laquium is indeed connected to Laqua somehow.
In The Approaching Shadow!, Spinel interrupted Liko and Amethio's battle and as an experiment, Spinel used the mist generated by the Treasure of Eternity on his , causing it to go feral, power up, and defeat Amethio's stallized in a single hit. Angered by the danger Laquium had caused in the past, Terapagos transformed into its Terastal Form and destroyed the Laquium with its power, forcing Umbreon back into its normal state and exhausting it. After trapping Liko and Amethio inside a cave and meeting with Chalce again, Spinel came to the conclusion that Terapagos and the Laquium are polar opposites.
In Liko and Amethio, after reuniting with Roy, Dot, and Friede, Liko told them what Spinel did to his Umbreon with the Laquium and that Terapagos destroyed it.
In HZ071, Friede asked Briar about the Laquium substance. While she had never heard of it, it still made her excited to know more about the world.
In HZ075, after Rystal was summoned by Pagogo at the Crystal Pool, she told the story of the Explorers to the Rising Volt Tacklers and Diana, including the incident in Laqua that unleashed Laquium all over the place.
In HZ083, the Rising Volt Tacklers discussed the properties of Laquium, noting its ability to empower Pokemon into a berserk state to be sinister and wrong. Mollie then theorized that Laquium could also have the ability to extend a person's lifespan and youth by increasing cell production and restoration, which was how Gibeon might have lived this long into the present. Elsewhere Amethio, Zirc and Onia discussed with Hamber about how Spinel might be intending to betray Gibeon in order to monopolize Laquium crystals for his own schemes.
==Effects and characteristics==
Laquium, aka Treasure of Eternity, are shiny, pink crystals that can be exclusively found in the deepest parts of the Pokémon paradise, Laqua. Its origins are currently unknown. It was also shown to be increadinbly unstable, which can cause it to grow and expand, causing a lot of destruction around the area. The Laquium's main characteristic is the ability to generate a pink mist, which has effects on , humans, and plants, possessing powers beyond human comprehension, which can even be considered as a source of life.
This mist can draw out the latent power of a Pokémon, however, it'll turn them vicious in the process, covering their bodies into a pink aura and even raising up their fur (if they have any). Depending on its use, it can expand the lifespan of humans, keeping their bodies younger for longer periods of time. Its mist may also stimulate the growth of plants, however, overexposure to the mist can actually start devastating the land, causing it to gray out and wither away. Mollie theorizes that Laquium's power is based on forcing the activation of cell replacement, constantly creating a strong, renewed body.
The Laquium also appears to have a connection to the Legendary Pokémon , specifically Pagogo. Terapagos also seem to possess a natural aversion to Laquium. Terapagos is also the only Pokémon known to be able of revert the effects of Laquium on Pokémon by transforming into its , absorbing the crystal's mist, and even destroying it. In high quantities, Terapagos isn't capable of destroying it so it's forced to seal it inside an energy shield instead. Spinel theorizes that their relationship is that of two are polar opposites.
==Trivia==
* Laquium's effects on Pokémon are similar to that of the substance R from the Detective Pikachu game and movie series. Both substances can empower and strengthen Pokémon, but also force them into a pained and berserk state.
