Multi-system species

As space-faring species began colonizing other star systems throughout the Milky Way, many planets were discovered with thriving populations of identical or near-identical plant and animal species, some recognizable from the colonists' respective homeworlds. In many cases, this was a result of the Forerunner Conservation Measure and manipulation by the Lifeworker Rate. In other cases, the cause was not as clear.

Terraforming

In the process of terraforming other worlds, humanity employed various methods to nudge local environments towards Earth-normal, as well as sustain a growing population of frontier colonists. Many of these involved the introduction of human agriculture and livestock, as well as forms of wild plant and animal life to balance ecosystems and air levels for human habitability.

Some of the species introduced by humanity onto alien worlds include:

Earth organisms

On other worlds, Earth-native species were discovered prior to human colonization.

The following is a list of known instances where Earth-native lifeforms were observed on alien worlds:

Beta Gabriel and Alluvion

• 

  Paelosur

• 

  Qothal

The Paelosur and Qothal, or "nightmare eel", were discovered on both Beta Gabriel and Alluvion, an Inner Colony and Outer Colony, respectively.

The Mantle of Responsibility

Although the Mantle of Responsibility was a wide-ranging belief interpreted in many forms by the Forerunner, and began as a more esoteric concept involving neural physics at the hands of the Precursors it did have some precepts that were put to writing. Those few have been collected here.

Numbers

• Didact's Number
  • Fifth Permutation - The peaceful one is at war without and within.

The Twelve Laws of Making and Moving

The Twelve Laws of Making and Moving were another group of written teachings pertaining to the Mantle, especially as regards the higher rates of Forerunner who had the ability to influence worlds.

1. The Mantle shelters all.
2. All is of the Mantle, and Living Time.
3. Preserve and protect all life, for all life has its place in Living Time.
4. Living Time is the joy of life's interaction with the cosmos.
5. Struggle and suffering is a part of Living Time.
6. Living Time must not be exempt of suffering.
7. The Mantle knows all truth, so bear it in your own heart.
8. The Domain is one with the Mantle.

Sangheili sayings

Much like humans, the Sangheili had many sayings and proverbs that encapsulated their cultural wisdom.

Sayings

• "A slight against one Kig-Yar is a slight against all Kig-Yar, but fortunately they're still fighting each other over what they should do about it."

Halo: Hunters in the Dark

• "To spill blood outside of battle is a great dishonor."

• "It is the warrior who wields the weapon. The weapon must never wield the warrior."

Ceremonial curveblade inscriptions

Many ancient ceremonial curveblades were inscribed with Sangheili proverbs on the hilt. Some examples of such proverbs include:

• "Words are most powerful before blades are drawn."
• "The sun warms those who stand before those who kneel in their shadows."

Spartan Battle Signals

Spartan-II operatives developed their own unique battle language comprised of silent hand-signals and LED HUD sequences, which later came to be utilized by Spartan-IIIs and presumably some Spartan-IVs.

Hand Signals

Gesture	Meaning
Two fingers touching helmeted faceplate	Indicates a smile

Status Light Signals

Spartan HUDs displayed LED status symbols for integrated members of a fireteam, capable of signaling in green, amber, and red. In addition to broadcasting a solid color, the status lights could be flashed in certain sequences to signal specific messages:
