S-1 Synth Matter was the earliest form of Synth Matter created by the original Promethean Council operation after nearly 300 years of uninterrupted research utilizing some of the most advanced technology ever seen by the Armada. Other than the effects described in the AZS section, the properties of S-1 Synth Matter are almost entirely unknown. It is too unstable to determine where the energy goes, but it absorbs the energy around it so it is impossible to directly study with traditional equipment. No replication attempt has succeeded.

Stage-2 Synth Matter

When the stability problems were discovered with S-1 Synth matter, the obvious thing to do was solve it. When they created a much more stable version of the synth matter, however, it was discovered the properties had almost entirely changed. Stage-2 synth matter was almost identical to regular matter- Down to the exact same subatomic properties and general structure. However, it cannot bond with regular matter nor antimatter. Perplexed, S-2 Synth matter has been researched more but appears to exhibit every single law and property that regular matter does, with the exception of it being entirely impossible to bind the two together. No replication attempt was necessary.

Stage-3 Synth Matter

Now even more intrigued than ever by their alterations of the fundamental particles of the universe, further alterations of the creation mechanism led to S-3 Synth Matter. All references to S-3 Synth Matter have been redacted, with the exception of one phrase- "God save us... The ponies are everywhere!"

Stage-8 Synth Matter

After several stages of synth matter even more unstable than S-1, S-8 Synth Matter was the first entirely stable stage since S-2. Initially, S-8 Synth matter did not display any unique attributes and seemed to simply be a clay-like substance, outside of not being identifiable as any known element or type of matter. However, when S-8 matter that was created in the same batch was separated to take to different labs, it was quickly discovered that whenever S-8 of the same batch was altered, every other S-8 sample from that batch was altered as if it was the one being manipulated. The uproar about this was evident quickly in the scientific communities that had clearance to observe the project, and S-8 was quickly mass produced for experimentation. Eventually, it was discovered that S-8 Synth matter utilized special "communication lanes" that did not rely on any form electromagnetic radiation for information transfer, and thus was not bound by the speed of light. These "communication lanes" exist by, in a simplified explanation, folding space between any two samples until they are the 3rd dimension equivalent of inches away from each other. When this occurs, they utilize specialized, extra-dimensional messages that travel through this 4th dimensional fold to their counterparts- The equivalent of an ultra-localized wormhole. When a sample is split with anything other than a high precision molecule laser into exactly even portions, the S-8 Synth Matter becomes unstable and quickly becomes useless. Unlike most other types of Synth-Matter, research into S-8 Synth Matter has yielded extremely productive standard matter counterparts. The Praenuntium, for example, resulted from research into how to send the 4th dimensional messages that were not bound by the speed of light without a wormhole. The success of the Praenuntium, and the rapid expansion of economic and sociopolitical success that followed gave new life to the Synth matter project. Samples of S-8 Synth matter are still occasionally produced and utilized for espionage messaging (extremely successful), teleportation technology (No progress), virtual reality testing (Small amounts of headway were made on portions of the project involving S-8, although S-11 has proven far more useful).

Stage-9 Synth Matter

S-9 Synth Matter is as unstable as S-1, but not nearly as useful. While the process of its degradation is far more explosive than S-1's, S-9 is far more unpredictable, and has been observed to degrade mere moments after creation, up until an unknown time after. When the Armda was forced to abandon their galaxy, there was a sample of S-9 that had been created in the first batch of the process that had still not gone off. Due to the high strength of the explosion, S-9 is often considered a possibility for warfare, if only the stability could be controlled to go off only when the Armada wanted it to. As S-9's primary property is explosiveness, reproduction of it is unnecessary.

Stage-10 Synth Matter

Information to S-10 Synth Matter has been classified to the highest level under the "Final Code" amendment.

Stage-11 Synth Matter

S-11 Synth Matter has the unusual effect of being highly capable of storing and transferring neurological impulses, but few to no other forms of electricity. While the exact method used to do this is highly complex and not understood by many except experts on S-11, the closest to a layman's explanation they have been able to provide is that the S-11's structure has intrinsic similarities to neurons and gray matter. It is a far more efficient, and far more reliable, conductor of neurological impulses than almost anything else. As such, research related to virtual reality and stimulation of comatose patients have increasingly utilized research and samples from S-11 in their designs, with success that has slowly been increasing. While a large portion of the research was lost when the old galaxy was abandoned, scientists, doctors, and corporate R&D groups with clearance have not given up in their projects. It is believed that the earliest versions of the VR technology will be released relatively soon thanks to the S-11 Synth Matter. Reproduction of the S-11 Synth matter and its effects has been relatively successful, but never to the degree of efficiency and reliability as the S-11, and often at a much larger expense. As such, most attempts to do this have stopped.

Stage-12 Synth Matter

Displaying the unique ability to transform regular and anti-matter into Synth Matter via an unknown process, experimentation into S-12 was canceled after event O-8-C, the destruction of sector 3-7-6 of the old galaxy, epicenter planet Ertya, research world. Several billion colonists died during that event, and without the quick action of the Armada military, samples of the S-12 would have made it out of the sector. Research into S-12 is forbidden by executive order, and most of it is redacted. Strangely, however, some portions of the research, instead of being redacted by the military, are labeled as having been redacted by the "Final Code" amendment.

Stage-15 Synth Matter

After several failures, another stable sample of Synth Matter was produced. Strangely, however, another sample of the same type could not be reproduced. After a small amount of research into this new type, the ship carrying the sample was destroyed by pirates, the remains being dragged into a nearby black hole. During this, however, another sample of S-15 was successfully created. With further research, it appears that only one sample of S-15 may ever exist. Should any more be created, they will not be stable enough to even observe for a moment. It is the only known stage of Synth Matter that can bind with all other stages. It gives a rather odd effect to each stable stage, while the unstable stages are temporarily stabilized, though they collapse again shortly after, destroying the sample of S-15.
