Ahoy!
Here's the abridged version of the introductory scenario for the campaign I am doing. Any feedback is welcomed.
The crew (Rogue Trader, Arch Militant, Seneschal) are but a group of smugglers in Calixis sector upon recieving information about a death of the Rogue Trader's uncle - a captain of a frigate class ship. Our Rogue Trader is next in the line of inheritence. As the trader dynasty to which he belongs has seen better days, they are reduced to resorting to people with questionable reputation. The PCs make haste to Port Wander, where their ship - Astrum Fidelis - awaits.
Upon arriving to Port Wander they recieve a massage from an old sevant of the Dynasty, a spy, who menaged to intercept information about Imperial Fleet's discovery of a capsule near the enterance to the Maw, bearing the crest of Rogue Trader's dynasty. It is said that there was one live passanger inside.
After introducing themselves with their new ship and crew the PCs go to the Fleet headquarters and demand seeing the capsule since it is the property of their dynasty. The commander agrees to give the PCs access to the capsule but declines them to see the passanger. When pressed the commander claims it is due to the quarantine, but the PCs get the impression that he is hiding something. Information from the capsule seems contradictory. The computer shows a general path from deep within the Koronus Expanse but it often cuts out. The dates shown by the computer seem to make no sense either as they jump back and forth.
Being suspicious of the commander's behaviour the PCs decide to investigate. They find out that the passenger was placed in the Research Block of the Fleet base. They menage to purchase blueprints on the black market and plot an extraction mission.
PCs sneak into the Reseach Block through maintanance tunnels. They succesfully bypass the security and knock out guards. Upon entering the room with the passenger they discover that he is in fact a humanoid xeno of an unknown kind. The alien is locked in a chamber filled with some kind of fluid. There are some strange scribblings on a table nearby. Some of the scribblings look like a depicion of some star system. When they enter the alien regains consciousness. With the use of strong telepathy he asks the PCs to free him and promises he means them no harm. When they decline he takes over one of the PCs and frees himself. The PCs take the notes and run. They immediately board their ship and leave Port Wander.
The notes they took from research block and the capsule point them in the direction of Heathen Stars. Their reasoning is that they might find a lost ship belonging to their dynasty. Plus the mystery draws them as well.
Naturally, I have plans for future scenarios but I am curious as to what would you do with such a beginning.
I might add that there is another Rogue Trader interested in their endavour. Their actions in Port Wander also drew the attention of Ordo Xenos. Both of the above are unkown to the players thus far.
