Shadows in the Void
Task Force: Valkyrie warships. If you see one and have a reason to suspect TF:V is on your tail, you might stand a chance with a well-armed ship and a healthy dose of luck.
Unfortunately for you, they travel in squadrons of three.
These angular ships are relatively small and their engines give off neither heat nor light, making them next to invisible. Halberd-class ships are typically armed with both long-range lasers — which seem more like focused lightning than a laser — and cluster missiles.
