Saturday, I will run my first game of Dark Heresy. It will probably be a brief 1 or 2 session run knowing the group I game with, but I've waited since the day Dark Heresy first appeared on the shelves at my local Game Store for a chance to run this game. On their first mission, the acolytes will search for signs of heresy on a fuedal world called Bastion Prime. Members of The Brotherhood of the Horned Darkness have hid amongst the ruling elite of Bastion Prime since the time of Saint Drusus, and only the steady disappearance of peasants gives away their presence before someone found a way to tip off Inquisitor Globus Vaarak.
Vaarak sends the PCs in to investigate allegations against one of the most prominent noble houses on Bastion Prime. Is there any thing I should insert into this scenario to make our maiden voyage into the 41st millenia a memorable yet enjoyable experience? The first adventure should remain somewhat low threat, and I don't want to bring in anything hyper lethal like blood letter or a daemon host during the first session.
