Sanctum (moon)

Sanctum, also known as Alpha, 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 4 families, The Primes. Because of their blood they rule here since.

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.

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.

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 the event that 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).

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 fences, 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.

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

Notes and Trivia

 * Before finding out that Alpha is a moon, it is erroneously referred to as "Planet Alpha".
 * Jason Rothenberg stated that aliens will be introduced on this world.
 * Season Six is set on this world.
 * Rothenberg said that we will learn more about Eligius III and when it came to this world.
 * This particular place in "Goldilocks Zone" refers to the world being far enough away from its sun to contain liquid, but still close enough to sustain life.
 * It was confirmed that new character, Russell lives on this world.
