Hi
-First I should warn that I will refer to the soul reaver quite a bit since the group just finished that aventure, if you wish to avoid spoilers you should stay away from my thread.-
So the players just got through the Soul Reaver adventure, all the normal important leaders died which would normally leave the players as the sole rulers of the Nexus but the Tau slaves played an important role in my campaign (the groups now dead kroot of course valued them as allies and got them to help, they got their pulse weapons out of the armoury and they made an effective fighting force in the battle. After the battle the Tau slaves made (without the knowledge of their empire) the offer that the explorers could become vassal rulers of the nexus under the Tau empire if they brought them back to their empire, they also offered other help for co-operating with the Tau and working for the Greater Good. Surprisingly the explorers accepted and are now about to smuggle them through the Jericho Reach. When they actually reach the Tau I will have the Tau try to make the Nexus a more regular world under their rule and try to gain as many advantadgeous deals out of the explorers as possible.
On the way there I plan on having them meet some Imperial Navy ships asking for help, being suspiscious and doing the normal navy stuff. But I would also like some other fun ideas for on-the way encounters (it is not a quiet place of space to travel through after all) as well as a good non-lethal deathwatch encounter, sending the deathwatch on them is too mean but they should still feel that the deathwatch presence is relatively high in this region. I am also quite confident that they will bring up some interesting in-group discussion, their last meeting with a marine did.
Ideas for the Tau interaction is also good, I have more confidence in this part but hearing other ideas is never bad.
