There is nothing but desolate emptiness in the void, as illustrated by the following poem found by Septimus Karne during his traversal of the void:

I find myself adrift in this dank nightmare,
Eroding my mind I scream out in despair,
Death beckons me closer and I do not care,
The void speaks to me, an I begin to scare,
As I begin to take my last breath of air.

Forever is not a constant for me, but my frail existence will be.

The void is traversed by using interstellar vessels of grand proportion, or use of the ancient waygates that still scatter along the torn and scarred planets in the region. The area is heavily controlled by Gith and Dawnikans, but something else is believed to dwell there, and they are known as Those beyond the Void.
