The Omega Lock/Omega Keys
The Omega Lock
The Omega Lock was built by the Solus Prime and the Knights of Cybertron on a far-away planet over a hundred million years ago. Using four different varieties of Cybermatter- the mysterious substance the Knights used to cyberform planets for colonization- the machine could harness the powers of the Allspark itself to perform miraculous feats. Solus built the Omega Lock with the intention of uplifting cybertronian kind, but when war broke out between the Thirteen and their followers, she realized that some would seek to use its awesome power as a weapon of unparalleled destructive capabilities. Solus wouldn't have that, and so she and Optimus Prime split the Omega Lock into five pieces. Four of these were taken into uncharted space and hidden away, while the fifth was taken back to Cybertron and placed in a vault inside the Sea of Rust, containing a map within its datatracks leading another piece. With luck, anyone who found the map and managed to bring all five components of the Omega Lock back together again would do so in pursuit of a selfless and noble end.
Recovering the five pieces of the Omega Lock is objective of our heroes aboard Salvation; the machine's power is the only thing that can restore the Allspark and save the race of Transformers from extinction. Bludgeon, a Decepticon warlord, also covets the Lock- with it, he can usurp Megatron as the Decepticon emperor, and remake Cybertron to his deranged designs. He and his legions of treacherous New Decepticons must not be allowed to have it.

The Blue Omega Key
Discovered by two intrepid treasure hunters in a vault beneath the Sea of Rust, Autobot scientists uncovered a map to the Omega Lock within the datatrax of a Golden Age-era datacard. Long though to be only a myth, the Omega Lock was now the only hope cybertronian kind had to save themselves from extinction, and so Salvation was built to carry a crew of explorers to find it.
Over the course of their voyage, the crew of Salvation have discovered that this artifact is more than just a simple datacard- it is, in fact, a piece of the Omega Lock, and it even holds a fragment of the machine's power. The Omega Key can activate and unlock dormant ancient cybertronian technology, and produces Blue Cybermatter, which can heal wounds and repair machines. If exposed to high amounts of energy, it can also randomly teleport objects and people.
The Blue Omega Key also contains an artificial intelligence, awakened when our heroes arrived on the planet designated OL-2006-2-C: an "echo" of a Knight of Cybertron named Atlantis, based off of his neural network so as to emulate his personality and retain some of his memories. Atlantis claims to have been one of the knights who helped Solus Prime build the Omega Lock, and thus likely knows a great deal about the machine.
An inscription running down the middle of the Omega Key reads like so: "The light of the Allspark shall shine even in the darkest of hours". Judging from the syntax, it appears to be a part of a longer phrase. No doubt the rest of the Omega Lock's pieces hold the rest of it.

The Green Omega Key
Recently acquired by our heroes on the planet designated OL-2006-2-C, the Green Omega Key is the next piece of the Omega Lock to fall into their hands, hidden by the Knights of Cybertron ages ago to prevent evil-doers from claiming its godly power. It is almost identical in appearance to the Blue Omega Key, though one notable difference between the two would be the different cyberglyphic inscriptions on the Green Key's surface. They appear to be a continuation of the Blue Key's cut-off saying, reading like so:
-and thwart the forces of chaos and evil-
The syntax of the glyphs indicate that the saying is still incomplete, and it is likely that the rest of the Omega Lock's components will have the rest of it.
Like the Blue Key, the Green Omega Key can activate dormant ancient cybertronian technology, and produces a variety of cybermatter which induces spontaneous growth of techno-organic flora. These plants can be harvested to produce toxins and cyber-venoms, or can be used to ensnare enemies. The Green Key also contains another "echo" AI, this one of another Cybertronian Knight named Hyperborea, who also worked with Solus Prime on the Omega Lock with Atlantis.
