Can it be done?
Here is the set up: The PCs, returning from Prol after the too-awesome events of Scrivener's Star , stop at a small way station. The Voidborn and Darkholders on the station have been there a very long time. The group's psyker has some bad dreams, and the few psykers on the station accost them on an open market-deck saying that "He is returning! He is coming back as he promised!"
Everyone is going around making the sign of the Aquila and touching door frames and rubbing ashes on their faces in anticipation of the Return of this explorer. Ships docked at the station are troubled, and try to finish their business before Who-Ever-It-Is gets home.
The sun is darkened in contrast to the tear in warp space as a Hulk precipitates back into normal space. It won't hit the station, but that doesn't stop everyone from freaking right the heck out any way. Amid this, would you as a player be inclined to get out, or explore the place?
Before you answer: Consider that my PCs will be 3rd rank when we get to this scenario.
Also, I'm thinking of an Ork boarding party, perhaps an old Imperial distress call or psychic call for help from within the hulk.
In addition, if anyone has ideas they'd like to share, I'd love to hear them. I just don't want it to be too similar to Shades on Twilight.
Ultimately, I think it will be discovered that the descendants of the original explorer are on board the Hulk, and would love to get "home" in some fashion.
