Alpha, also called Sanctum, is a moon sharing atmospheric similarities to Earth. It is located in the Goldilocks zone of a binary star system, meaning it is in the habitable zone and has two suns. It was colonized by a team from Earth made up of four families, the Primes. Using Mind Drives, they continued their rule here for over two centuries.

Overview

The atmosphere is similar to Earth's, containing 77% nitrogen, 22% oxygen, 0.5% of argon, 0.2% of carbon dioxide, and small amounts of a new, unidentified element. Due to having two suns, it was believed that the moon's surface has higher radiation levels than pre-apocalypse Earth. To counteract that, Eligius Corporation used the Nightblood serum on the members of Eligius III going to the moon. However, Nightblood was later discovered to be unnecessary for the survivors of the Battle for Eden, since the radiation levels are revealed to be good.

Celestial Events

Red Sun Eclipse

The moon undergoes a celestial event in which the two suns eclipse, triggering the release of a psychosis-inducing toxin from the plants. During the eclipse, sonic anomalies are sometimes caused by molecular vibrations in the air and trees. When exposed to the toxin, all fauna are affected and goaded into violence. Those killed after the eclipse is over are consumed by the plants and trees.

Temporal Flare

A temporal flare seems to be a green light source in the sky shoots out other green flares that burn and destroy anything they touch.

In "The Gospel of Josephine", Xavier notices a Temporal Flare going on. He tosses Diyoza the rope and tells her and Octavia to get out and run. Diyoza gets out, but she realizes that Octavia has no time. She tells her she will return. Octavia submerges herself in the quicksand like stuff and survives the Temporal Flare. Diyoza manages to dig Octavia out and they run after Xavier.

History

In 2045, Eligius III arrived to this moon. The Eligius Corporation was looking for a source to tap for oil, since Earth's oil reserves had run dry. The crew had underwent the blood alterations from Becca Franco's Nightblood serum, in case the radiation levels were too high. According to Eligius IV's records, if they ever reported back, it was after Apocalypse One, when no one could have received the call. The true results of their arrival remain unknown.

Centuries later, Monty Green, after 30 years of research, cracked the code-locking on the Eligius III files while on Eligius IV, and set the mothership's coordinates to travel to the new planet (not yet identified as a moon). The ship's journey lasted 75 years. Upon arrival, Monty and Harper McIntyre’s son Jordan Green woke from cryosleep as his father intended. He went on to follow his father's instructions and woke Clarke Griffin and Bellamy Blake. He shows them his father's video files, explaining their life on the mothership, the destroyed status of Earth, and the new world they could call home.

Lifeforms

Native lifeforms are largely floral in nature. Nearly all existing faunal creatures were classified by Josephine Lightbourne in four evolutionary branches: Insect, rodent, reptile, and the less easy to identify, coined "Guaiwu" ("freaks" in Mandarin).

Bugs

S6Titles Bug

A bug

In "Sanctum", Jackson can be seen with a native bug contained in a jar. Soon after, a swarm of the bugs attacks and chases the exploration team through the radiation shield, into a settlement.

The bugs appear to be omnivores, shown to eat both meat and plants, as observed by Jackson. The bugs travel in swarms when hunting. They also appear to be strong, the bug Jackson had trapped repeatedly slamming into the glass without injury. The bugs avoid fire. 

The bugs have hook-like legs and round eyes, like that of a fly. They have a small tail and hidden antennae.

Snake (Kepa-She)

In "The Children of Gabriel", there appears to be a hideous snake, "Kepa-She" in Chinese. It can degrade the poison from a body, caused by being exposed to the seaweed during the eclipse.

Seaweed

During Red suns, seaweed can move around ponds or lakes and crawl into someone like a tapeworm. It releases a toxin within the victim practically killing the host. The person can be revived by the Kepa-She snake like John Murphy was.

In "The Children of Gabriel", during the red sun, seaweed crawled into Murphy when Bellamy almost drowned him in the pond in the village. Cillian lets the Kepa-She bite him reviving Murphy.

Trees and other plants

During the red sun, trees and other types of growth become dangerous as they can release a toxin making people and bugs psychotic. If a victim dies near plants, the plants will "consume" the dead, even if there is no red sun. They can also eat fauna and bugs.

Locations

Sanctum (Settlement)

Main article: Sanctum (city-state)
Sanctum settlement 6x01

The settlement, also called Sanctum.

The Sanctum settlement is located within the radiation shield.

Ryker's Keep

Back in the early days, Ryker built a temporal place inside the cave system under the settlement. The purpose was to hide there during the Eclipse, so neither citizens or Primes would be exposed to it.

Offering Grove

The place in the woods near the settlement which serves as a cemetery for the dead Sanctum citizens. According to traditions, the bodies are offered to the trees, so their souls could be in a better place.
