The Slumber

The Slumber was the Astral Traveler where some of the party was travelling on.
It was a relatively small vessel, for those who cannot afford the larger and faster models. Still, it was a sturdy and long serving vessel that had made many a trip through the void.
The ship was seemingly hijacked when the Herald of the Void took control of the captain's mind, Mercer and seemingly steered him towards collision with another astral traveler.
As the last image of it was exploding from within and breaking apart, it is safe to say that the Slumber will forever sleep now.
