The highly advanced human civilization however couldn't remain hidden from the cosmic neighborhood. A species of highly intelligent and malevolent aliens located far into the Milky Way's central part and thus remaining undetected to the humans, had been keeping records of the progress of humans over centuries. They were keen on expanding their dominance within the galaxy.

They had scrutinized almost every planet in the galaxy for intelligent life but could only find one such civilization- The Humanity. These aliens were far more advanced than the humans and had been extracting enormous energy from the central black hole using structures similar to what humans theoretically called Dyson Sphere.

These aliens were a warlike race and had cleared almost all the planets within their radius of one thousand light years to obtain material for their powerful machines.

They had reached such levels of advancements that they had increased their lifetimes to millions of years. Their physical strength was comparable to a thousand military soldiers of the humans.

They had developed stellar missiles that would steal the energy from a star's core and reach the target through bending the space-time fabric and destroying it within nanoseconds of their launch. Their smallest warships were a few times larger than the mothership Andromedae T-1 and had invisible cloaking technology over them that would render them almost invisible to any kind of electromagnetic scanning and heat signature. They possessed quantum weapons which harnessed the phenomenon of quantum entanglement which could be used to destroy the orbits of planets and other objects within a star system and causing chaos for the inhabitants.

They got the first light about the human civilization way back in the 21st century when their interplanetary probe Oumuamua had entered the solar system and were since then monitoring the humans development through their advanced tools.

Their long term mission was to access the other dimensions and harness the power of all the galaxies within the universe into a singularity and escape this universe into the multiverse dimension and other higher levels.

Powered by dense core of antimatter, their spacecrafts were able to bend the space-time fabric to such extents that enabled them to effectively travel a thousand times faster than the light. Their warships were way stronger and advanced than what even a human scientist from the Intelligentia could have ever imagined.
