A Trap

Old military complex, or what was this place? It was definitely in use. The map led them through poorly lit corridors... and sudenly turned blank.
They could hear it now.
Sounds.
There were people. Soldiers.
They tried to hide, but it was too late. They were attacked...
„Single shots!“ Thorin ordered calmly.
The soldiers didn’t take cover.
The bullets didn’t stop them. Couldn’t kill them. They were dead already. Wraiths. Only half there.
„Portal, now!“ shouted Thorne.
„This way!“
They ran.
They jumped.
Darkness. Lights in the distance.
Thorne loudly sweared.
They lost. The battle and the link as well.
