Hey everyone. I am the GM for a group that is just starting a DH game, and for this first campaign I am planning on mainly using the published adventures. The problem is, that while I want to run the missions from Purge the Unclean and then, depending on what rank the PCs end up, go into House of Dust and Ash and then the Harlock legacy missions, what I don't want is to have it look like I'm setting them up to do battle with the Serrated Query like in PtU and then randomly run off in a completely different direction, that is the Harlock Legacy.
So my question is, does anyone have any good ideas for how to tie the two together, or at least transition smoothly?
