Cyberon invasion of Ecto-Space

The Cyberon invasion of Ecto-Space was the attempted cross-dimensional invasion of the pocket universe Ecto-Space by the Cyberons.

It occurred in 2963 as part of the greater Cyberon War in the main universe. (COMIC: Before the Storm)

Jokastarnan forces, including Sergeant Dro'Ken, fought against the invasion. The Mistress, who was also native to the primary universe and had become a protector of Ecto-Space, witnessed the invasion and how the Cyberons were eventually "beaten". Years down the line, while delirious under the influence of Sherwoods disease, she briefly hallucinated that she was under attack by a squad of Cyberons. (PROSE: The Choice)
