After the mass exodus of the Lyrians, they settled and rebuild their civilisation in Andromeda, Hyades, Orion and many star systems.  Civilisation rise and fall and many started to explore the vast universe for resources.

THE CONFRONTATION

At the Ring Nebula, they found a wormhole that enables them to operate a stargate and allow ships to hyper jump to any location in the universe. And the Republic Alliance build the Citedal Stargate which poses a threat to the Imperial Empire (or Orion Empire). 

After several warnings by the Reptilian, the Republic Alliance went ahead and activate the Citedal Stargate.  The Reptilian sent an assault fleet to disable the Citedal stargate and retreated back to their homeworld.  The Sirian fleet pursued the Reptilian fleet to their homeworld but it was intercepted by the Draconian battle fleet. The Sirians attacked the Reptilian and Draconian fleets and was defeated.
