“Look out, everybody, things are about to get awesome!”
Nekrotafeyo is the homeworld of the Eridians and is the setting for the final chapters of Borderlands 3. Now devoid of civilization, it has been desecrated by Maliwan in their attempts to gain a deeper understanding of Eridian technology.
Believed to be a fairytale, Nekrotafeyo housed the Eridian civilization up until its sudden disappearance. Relics and writings on the planet reveal that the entire population of the planet was sacrificed to power the Machine, which was used to incarcerate an ancient threat to the galaxy. The perpetrator of the sacrifice, a Siren named Nyriad, becomes haunted by her actions despite the relatively positive outcome, and seals herself within a Vault on the planet.
Years later, Typhon DeLeon and his wife Leda DeLeon leave Pandora in search of Nekrotafeyo. While making love on their rocket, they crash-land on the planet, leaving them stranded. Despite this, the two declare the planet to be their new home and begin exploring, where they discover the unreachable entrance to the Machine and the planet's Vault. After defeating The Serpent and opening the Vault, the two make profound love within the Vault for their success, causing Leda to eventually become pregnant. Several months later, Leda gives birth to Tyreen and Troy, both of who are revealed to be Sirens. Fearing what the rest of the universe would do if they ever found Nekrotafeyo and their all-powerful children, Typhon and Leda propose they never leave, leaving the family to remain on the planet for years to come.
Sometime later, Tyreen accidentally kills her mother with the use of his Siren powers, leaving Typhon to take care of the two children alone. Eventually, the two grew bored of their planet, and after being filled with Typhon's stories of adventure across the universe, decides to abandoned their father on Nekrotafeyo in search of The Great Vault.
In Borderlands 3, the Crimson Raiders come to Nekrotafeyo seeking a way to prevent the opening of the Great Vault after Tyreen and Troy begin the process. Typhon reveals himself to the heroes and highlights the existence of the Machine, a great planetary mechanism used to originally seal the Great Vault. Dispersing resistance from stranded Maliwan forces, resident Guardians and interloping Children of the Vault, the Crimson Raiders attempt to reactivate the Machine using the four extant Vault Keys, but their efforts are ultimately foiled by Tyreen, who irreparably damages a key part of the mechanism. In the ensuing struggle, Tyreen mortally wounds Typhon before escaping back to Pandora to witness the emergence of The Destroyer. With his final breath, Typhon asks the Vault Hunters not to be the last of their kind before passing away. Using her Siren powers, Patricia Tannis opens a portal to the Destroyer's Rift for the Vault Hunters to return to Pandora.
- Runes on the planet's surface indicate that Nekrotafeyo means first landing, suggesting that it may not be the first Eridian foothold in the universe.
- The name of the planet seems to be a variation of the Greek word nekrotafeio (νεκροταφείο), which translates to "cemetery".
