It's 132 Miles long, has more firepower than most planetary systems, carries it's own fleet with hundreds of warships with each one millions of years more advanced than our own vessel and they already know who would win in an engagement with us because they can see the future???
Well there is only one thing left to do...
Bring her about. load torpedo tubes, raise shields send a direct alpha alert code 1 to Terra relaying our position and bring all guns to bare!
History recorded that on one day in the Year of the Emperor M39.461 the imperial warship Holy Sword was reported lost when it's on board astropath simply stopped transmitting in an area of space generally associated with the Eldar pirates of the designation Saim-Hann.
What I could never understand is, if they can see into the future, why does so much bad shit happen to them. No more than any other race in 40k mind you, but wouldn't they be able to avert, for example, having their craftworlds 3/4 eaten by tryanids?
Lt: i dont know milord but it is Eldar
Magos: Sir that is a craft world
And the Eldars are the one ho are gona kick ass and no a nother way.
Cheers for you.
