Mystery aliens in Halo

This thread is made to list, and discuss the Meddlers and other mysterious species in Halo. Seeing as I see plenty of discussion ready for this subject.

Alpha Halo

Unknown Ship: Halo CEA Terminals

A ship crashes onto Alpha Halo, it being the first species to appear to Guilty Spark. Guilty Spark becomes hopeful for the next visitors.

Meddlers: Conversations from the Universe

Revolution 56-11.333: Ho hum. Eons of inactivity and perfect stability. Then everything happens all at once.

A primitive, hegemonizing swarm calling itself The Covenant has landed on installation 4. Apparently seeking something specific. Exploring! Meddling! I've seen it all before. They'll record what they see and they'll leave.

This says that Guilty Spark has encountered other species, and they have Explored and meddled with Installation 04. These meddlers cause Guilty Spark to become hostile to anything that comes near Installation 04 as shown in the first Halo CEA terminal.

Delta Halo

Possible Meddlers: Halo Universe Section Delta Halo

BACKWASH - WAR GAMES MAP_SET/: 098-8 Delta Halo’s primary Flood containment facilities resided in remote regions of the ring, including a series of vast bogs and swamplands. It is believed the Forerunners did this to discourage potential intruders or at least obfuscate the truth of the facility below. At some point, the Flood breached the containment facility, leading to an outbreak and formation of a Gravemind. It is unknown whether a system malfunction or outside meddling led to the breach.

This shows that outside meddling could of led to the Gravemind forming.

System of Miasmic Giants

Unknown Species: Broken Circle - Page 30

The old warrior rubbed thoughtfully at his scarred eye socket. "Many cycles ago, I was the last survivor of a vessel brought down by hostiles - we never knew what race it was. They did not speak a civilized tongue. All this was on the far side of the galaxy from here, in the System of Miasmic Giants."

This is a species that nearly destroyed 'Crecka's ship in the System of Miasmic Giants.

Line Installation 9-12

Unknown ships 2: Halo 4 Wreckage Map

Unknown ships appear around Line Installation 9-12

Nethrop aliens

Halo Oblivion - Need to expand

Unknown Location

Prisoner: Halo Reach Map Solitary

A prisoner escaped from this location

Confirmation other species exist: Canon Fodder: Bulkhead Banter

CHeeeezyy: Are there any other kind of sentient beings (as like if they knew how to make tools and stuff) in the Milky Way galaxy?

A: The short answer is yes, the Forerunners indexed and reintroduced many sentient species into the Milky Way galaxy. The longer answer is that only a fraction of these species have gone on to build tools or achieve even Tier 7 (preindustrial) signature technologies in the millennia following the firing of Halo; of those, only a handful have been encountered by humanity in the Orion Arm region of the galaxy. In fact, not even every species that fell under the yoke of the Covenant have been contacted and catalogued by the UNSC, as the Prophets did not deign many worthy of trading service for salvation within their fleets and the Sangheili kept few records of civil affairs.

Number of catalogued species: Halo Silentium - Page 18

"But as Catalog I am aware that she has studied and favored one hundred and twenty-three technologically capable species across three million worlds within the explored regions of our galaxy. How many of these she will seek to preserve, it is not my job to predict or even to understand."

At least a total of 123 sapient species existed in the Forerunner ecumene

Cancelled Halo Project

This Halo project[1] was a internal only experimental project, never meant for anything more,[2] that may never see the light of day that Jeff Easterling worked on.[3]
