Eureka (primal)

Eureka is a primal from Final Fantasy XIV: Stormblood introduced in the Forbidden Land, Eureka instances. It was imprisoned on the Isle of Val.
== History ==
=== Early life ===
The primal Eureka was created during the Third Astral Era by an unknown people. A being with the ability to synthesize its current "master's" wish, it drew upon aether to create many deadly objects, including primal-like weapons that would transform their users into beings confused with eikons. During their research, the Allagans called these weapons "trigger weapons". The eikon was sealed away in the depths of Eureka Orthos, to hide it from those who would misuse it, and the researchers were forbidden from uttering its name. Over time, the eikon forged various weapons, among them the Excalibur, which was pierced through Artorius's heart, and the Zantetsuken, which possessed whoever wielded it to become Odin. In the days before the Fourth Umbral Calamity, the researchers knew that the rebels were closing in and keeping the entity's powers out of their clutches was a top priority. So the primal was transported to a distant location.
In the Sixth Astral Era, it was discovered by Galuf Baldesion and his associates, who entrapped and imprisoned it at the center of the Isle of Val, recognizing the threat it posed if it were to fall into the wrong hands. Galuf and his companions began seeking out the weapons created by Eureka, sealing them away in a vault on the island called the Baldesion Arsenal. Eventually, Galuf would go on to found the Students of Baldesion, and the scholars who would come to join him would dedicate their efforts to experimenting and documenting the capabilities of Eureka, as well as researching Hydaelyn and the Echo, all in an effort to one day destroy the primal.
Eventually, its location was discovered by the Ascian Emmerololth. Unwilling to let the Ascians get their hands on Eureka, Galuf ordered the evacuation of the island before joining with his companions to invoke a spell that drew the entire island into the Lifestream. Emmeroloth's essence was permanently scattered into the raging aether, and those who still lived eventually became one with the Lifestream themselves. With the entire island now outside the corporeal realm, Galuf hoped that Eureka would remain out of reach.

From within the Lifestream, Eureka used most of its aether to push the Isle of Val back into the world. When Krile and Ejika Tsunjika investigated the island, they discovered elemental forces raging across it. The two searched separately for an explanation, during which time Eureka's avatar approached Ejika and gave him a blade it had created. Seeming to fall under Eureka's sway, he used the blade to destroy the aetheryte network preventing the primal from absorbing aether. With the network destroyed, Krile devised a means of restoring the ward, but she would have to disable the restraints within the headquarters of the Students of Baldesion that were keeping Eureka contained.
Upon deactivating the restraints, Ejika appeared with Eureka's avatar. Revealing that his alliance with Eureka was a ruse, Ejika threw the blade to the Warrior of Light who, being immune to Eureka's control, struck the avatar down. Ejika informed Krile and the Warrior of Light that with the avatar destroyed, and with so much aether having been expended in returning the Isle of Val to the world, the primal was weakened enough it could be destroyed. Krile objected, knowing that Ejika would have to sacrifice himself to do so, and insisted that with the Ascian Emmerololth gone they could reseal Eureka and have time to find a better solution. In the end, they left the decision up to the Warrior of Light.
After following through one of the choices, the Warrior of Light led a raid into the Baldesion Arsenal, where the Galuf had sealed the most powerful weapons created by the primal. They destroyed the weapons within, and following up as a result, they resolved the situation left by their previous choice, resulting in both Eureka being destroyed, and Ejika being retrieved from the Lifestream.
=== Final Fantasy XIV: Endwalker ===
Despite Eureka's destruction, one of its weapons, the sword Excalibur, remained sealed in Eureka Orthos under the Crystal Tower still embedded in its host, Artorius. The Warrior of Light ventured into the deepest part of the laboratory and vanquished the weapon.
