I admit it...I am the Vasari nemesis.  It was me all along.

Please don't tell.

I like the idea of an extra-dimensional sort of bad guy.  I keep thinking of the ship that came back after 50 years in the movie Event Horizon...that sort of badness.

It's either that or their grown up kids showed back up at home and wanted to move back in....maybe Lady Gaga too.

sorry i was a little vague with the op.

 the reason it could be an evolved vasari race is because it started at their home worlds.  the most secure planet in anyone;'s star empire.  also this enemy catchs up to them one generation after they settle down a little to rebuild and gather resources.

the reason it could be a human race is that when they smacked into the humans from earth, we stopped them in their tracks and we didn t even have any warships when they arrived.  well a few to take on the pirates.  but no caps just some ff.

in either case the vasari are cowards, the first true fight on their hands and they run away.

Look at the Vasari tech effects in a late game--they have incredible power and that's their "mobile forces" on the run.  In the day, their empire must have been epic. 

Now look at the primary areas where they focus tech:

• Gravity/Phase Manipulation
• Genetic Modification/Augumentation
• Highly Developed Multiple Purpose Nanites

Then you look at the game title and premise, "Sins".  So the question is, "What is the sin of the Vasari that unleashed such judgment on them and who did they sin against and what enemy has it brought to them?".

If their technological power caused their dilemma, I think the gravitic/phase specialization points to a real possibility of a breach in their universe to "something else".  Maybe they opened a hellgate , summoned Cthulhu or transgressed into the domain of godlike beings or perhaps it is something they did to themselves...think of what a Vasari "Umbrella Corp" could do. Maybe Milla is after them   It could be they opened a portal to another universe or dimension adjacent to phase space or on the other side of a wormhole, modified themselves augmented with nanites to survive there and tried to expand their conquest there--only then to find things weren't simply a matter of mere arms and force and that they didn't just go in but let something out that they can't put back.

But I personally don't think its simply that they found as technologically more advanced race and are fleeing it.  I think it is something that absolutely terrifies them for their very existence.

The one thing that could do that for sure would be something that can twist the very nature of reality and turn their universe into a living hell.

If you saw in the last Battlestar Galactica series, when it was revealed that "god" was behind human and cylon creation, the more atheistic cylon simply couldn't deal on that level and then blew his brains out.

I think the Vasari did not find another race simply "more technologically advanced" than themselves--I think they found one so fundamentally different and alien and powerful that it shook their confidence and reality.

So it has to be space ponies.

But in defense of Event Horizon--how would you react if not only did a ship come back after 50 years and the recovery crew went mad but then you discovered the original crew was still alive and would never die suffering horrible torment and the thing that had them was now going to rule your universe too.

Muwahahahahahaha...yes, foolish mortal...beaten indeed.

Why would they flee then?

the evolved vasari developed psionics.

Isn't that what sequels are for?

the vasari are only able to sit on their butts for a single generation before the enemy catches up to them.  meaning not only can these guys beat them but their able to track them through space.  or the new enemy is born and takes a generation to grow up and become a threat.

No, I'm pretty sure he killed himself because he had apparently just been betrayed by the Final Five, resurection technology was lost for good, his comrads (I don't want to call them friends) were all dead or in the process of dying, and the humans would probably kill him too. And they were all about to fall into a black hole.

dont we humans always have to pick up the pieces.  besides as i said when the vasari started their attack on humans we had no warships except a few pirate fighters.  we humans not only fought them to a stand still but we are now defeating them long live the traders.

Everybody go read the first book of the safehold series. You will understand how it is possible to escape. Space is vast.

I like the tear in space idea, like species 527 or whatever it was in star trek. The altered dimension is cool too... i'd love to see organic ships.

One lof the Babylon 5 movies was like this.  I forget the name but it was like "Lovecraft in B5".  They found a Vorlon artifact that opened a gate to another universe only the guys on the other side were very nasty and very advanced.  I thought it was a cool "long episode".

These ideas years back were things you discussed with others but NEVER saw in a movie and often not in books.  Now everybody does them.  Darn.

I am not a big Hellboy fan but I did love the ending scenes of the first movie.  There is nothing more scary than pure alien evil that comes from somewhere else, is unknowable, unstoppable and wants you personally to suffer

Guys, guys. The stuff chasing the Vasari are obviously Reapers.
