|“||"How does an Island of Light sound to you, John, huh?"||”|
|— Thelonious Jaha to John Murphy [src]|
Becca's Island, also known as A.L.I.E.'s Island, is located off the northeast coast of what was the United States. It is east of New Jersey and south of Long Island (New York).
Before the Nuclear Apocalypse, this island was used by Becca and her team for the A.L.I.E. project. Afterwards, it was used by A.L.I.E and her followers. After A.L.I.E. is destroyed, a team of Sky People led by Abigail Griffin use the island to research Nightblood.
Located inland, this pristine three-story building was used by Becca and her team while designing the artificial intelligence, A.L.I.E. It is equipped with holographic technology, which allowed to project a hologram of A.L.I.E avatar anywhere inside. The Mansion has the modern 21st century technology and a swimming pool. There are drones that usually hover over the building.
After determining that A.L.I.E. was too dangerous, Becca used the mansion to confine the AI until Jaha unwittingly delivered her the means to leave.
The mansion is first seen in "Blood Must Have Blood (Part 2)", after Jaha follows A.L.I.E.'s drone. In "Wanheda (Part 1)", Murphy finds his way to the mansion after being released from the lighthouse bunker.
In a flashback in "Thirteen", Becca tells Chris to hide in the lighthouse bunker. In the video shown in "Blood Must Have Blood (Part 2)", Chris records his last words and suicide while he's in the bunker.
Becca's laboratory is located in the middle of the island. It consisted of six levels and ten different areas, including an office, radiation chamber and many other things.
The concrete entrance of the lab was destroyed by the death wave.
