warp gate

In the Charadom Sector of Imperial space, a mysterious ship once thought lost, appears in the Never light solar system. It carries the name of a lost ship belonging to the Fire hawks Chapter Astartes, however it has been transformed by the warp. The name of the ship is "Infernus".After watching the ship for several days drifting through the sector, the Imperial guard take caution approaching the ship. However once in boarding range, a warp rift opens and the Infernus vanishes as fast as it came.
All Imperial records of the encounter have been washed from the official imperial record. All witnesses claim it was merely an Imperial Navy training exercise. Anyone who denies these claims are to see Commissar Nero Crux immediately for re-education, on imperial etiquette.
