Well, time to step up! I've been looking for the theme describing best situations throughout FS history, and so it is.
"... by the time of the Great War.
Shivans came. They are enemy unknown. A threat to all living species. They came for Vasudans. They destroyed them, glassed their planet. Now the are coming for us.
~Entery from unknown lieutenant, GTD Bastion"
"Earth was helpless at the time, exposed. Their doom, our doom was coming... and nothing could stop it. SD Lucifer was an invincible warship, with weapons and defences unseen to this date, ship that moved around and through our forces, like they would be nothing, like a wall of paper. Terran homeworld - Earth, was doomed." - though the admiral as he hurried all of his crew to extends of their limits. Scientists found the way how to stop this monstrosity, the Lucifer. And the Bastion was the only ship able to stop them in time. It was only a one chance... there was no room for failure.
Everyone onboard was terrified... they all had families on Earth, their homes... their cradle... all was about to be destroyed, and there was almost no possibilities of striking back... that what was killing them most... inability to stop it. Their fear was even greater then their anger, what if... Bastion will not make it in time? What if Lucifer arrives in Sol before they can intercept the shivans?
The ultimate question was shadowing everyone, every person onboard the Orion as it struggled through subspace, inbound for the Sol jump node, their reactors pushed to the limits... strike wings equipped with the best they could....
All their effort was in-vain. Quick scan indicated that Lucifer was already at the node.... too far for Bastion to reach it in time... It was too late...
In act of desperation... the bite of cornered rat, they launched everything they got, in hopes... that Fighters might reach the ship in time, and save our race from the impending doom.

They cut through shivan wings like a hot knife though butter. They could not allow themselves to be stopped. Their mission was far too important to fail it... all of the Terran race survival depended on these few fighters capable of subspace travel through jump nodes. They done it.... they arrived at the node... a grave moment... did the Lucifer arrived in Sol by that time? There was only one way to check.... they followed the great nightmare into subspace....

And there he was, vunerable... can it be stopped in time? Can our very lives be saved? Can we confront the nightmare of the shivans, and overcome it...?

and that was for my 2 screenshots. Well, im not even sure if such an extended background is even permitted here, but honestly, I have no real idea how one can inspire the feeling of fear with just a bare screenshot... FS isn't suited to do that... so i thought a bit of backstory can add to the meaning of the months theme.
