Sedaaro Forerunner

The Path Kethona Forerunners were an ancient relative of Forerunners. After the Forerunner-Precursor War ended, the ancestors of these Forerunners disobeyed their commanders orders in order to invoke the Mantle. Some were executed on the ships and others were in turn abandoned on an unidentified planet in the Path Kethona galaxy. These Forerunners were the only ones to survive, due to Forerunners not wanting to return to the Ecumene because of the shame, fear and knowledge of their actions.

Species
Following is a list of different Forerunner species, and possibly genera, that evolved naturally or artifically on the unknown world in the Kath Pethona galaxy. All life was likely wiped out when the Master Builder fired the Omega Halo in the direction of the Kath Pethona galaxy.

Sentient Forerunners
These Forerunners are most like the original Forerunners they separated from 10 million years prior to being found by the Librarian. Their changes were most likely caused by natural evolution, evolving to more simpler forms to suit a more simpler way of life. The obvious differences with the 'regular' breed of Forerunners is that they have 5 digits on hands and toes instead of 6 and they have grey, Human-like teeth, apparently in contrast to regular Forerunners. The nose was still classically Forerunner, but their fur patterns were more expressed. On average, they were two thirds the height and mass of a Manipular, being 1.5 meter in height. Their build was broad shouldered, as well as a broad midriff, thick legs and short arms with long, curly fingers. They also eat meat, in contrast to the regular Forerunners. Their reproductive system is also highly different from regular Forerunners.

Herbivor Forerunners
These creatures were twany-furred, 500 kilogram large animals that preferred squatting. Although their faces still largely resembled Forerunners, with eyes closely spaced. Their digits and phalanges were still recognisable Forerunner.

Besides these herbivors, it is noted to have other forms of animalistic Forerunners not specifically mentioned.

Plant Forerunners
These creatures were genetically altered on a large scale to become plants and mosses. The plants would serve as a food source for the herbivoral Forerunners, which in turn supply the sentient Forerunners with meat and thus being able to maintain a lasting biosphere. They are described as being scrubby and set low to resist the wind. Some are in the form of grey-green bushes and others have stalks topped by spiky leaves.

The Moss or Lichen Forerunners are orange and fibrous. They apparently can move on their own and scratch markings in rocks with their roots from memory.

Technology
They only had limited technology, consisting of fire, cerametics and some metal-working. They also excersized population control.

Their villages consisted of simple mud and stone houses and buildings not taller than 1 or 2 stories, or wider than 5 or 10 meters. They were surrounded by mud and stone chest high walls.

They had a simple language entirely different then any other Forerunner language. As well as a complete absence of rates and forms, indirectly causing the sexual demorphism to reduce.

However, they did retain some form of advanced technology, as they had microbiological 'agents' in both their blood and mouth, which would transfer memory and understanding from Forerunner to Forerunner through biting. After this initial biting, touching is sufficient to spread information from one individual to another. They do not enjoy it, but occasionally it must be done to the most ignorant. They form Quorums of 100 Forerunners linking hands to gain information from ancient times.

They also created a biological 'Domain' through the use of Memory Spores, which when inhaled could reveil the entire past of the Path Kethona Forerunners and why they were brought there. They had this memory saved in the spores and in the mosses because it was unbearable for themselves to cope with some of these memories and because they wished to be themselves and not live in the past. They still went to the location of the spores whenever they wished to know about tradition or settle a dispute.
