Yeah, but its a long one, so I'll write it up later.
Well I did say I'd write it up, so here we go.
So in order to spice up our campaign when we were generating back grounds (this was separate to our DH campaign though plenty of our GM's lore was similar) he let us take an additional bonus by selecting an enemy similar to how when generating a Space Marine in Death Watch you select an enemy.
Anyway, 3 out of 4 of us selected a Merchant Guild, the Sons of Levanthi, because we thought they'd be push overs.
Oh god were we wrong.
My character (a somewhat liberal tech priest explorer) had lead a heist on one of their vaults getting a very fancy DAoT las pistol, our Rogue trader had scammed one of the leaders out of a Goliath Fabricator and our shooty mc shooty person had lead a one man assault on an important refinery of theirs earning her a load of cash.
Needless to say we were not well liked by them, which resulted in them making our lives hell at every opportunity imaginable, slowing down our progress and worst,
doing it completely ****ing legally.
For example they'd insist on making sure we had to go through ALL of the checks before we left Port Wonder if they could get to the people we had to bribe to leave fast. This meant that every stop on Port Wonder became a race to try and get in grab what we wanted and leave before they realised we were there and started causing us hell (like this one incredibly annoying time when they bought all of the Iron Ore on the station. Every. SINGLE. PIECE.)
It got to the point that we were buying things like swapoutable heads for our ship and drives that we could reconfigure to give off different frequencies to give us more time between stops.
And that was nothing compared to them trying to ensure that we would never be able to get the best Navigators, though we were able to eventually get around that by establishing a permanent contract with the House of the Area.
And of course they were always trying to get us in trouble for our semi legal activities like that one time they tried reporting us to the Inquisition for acquiring the Cold Trade artefacts to give to a different Inquisitor (that one back fired like hell on their part as the Two Inquisitors started causing each other no end of grief over that. I mean we still got paid, but still.)
Slightly less amusing was them bringing an entire battalion of Myrmidons on our heads because of "tech heresy." Please I was liberal not stupid.
Took a lot of checks and the deployment of the Callamus/Alpha argument before they stopped ripping our ship apart to find the tech heresy and the bastards STILL confiscated a decent chunk of my archeotech store... I mean sure it was the stuff I had copies off, but still the bastards.
Because of them we spent most of our time in the Kronus Expanse as far away from them as possible, which to be fair was incredibly profitable, as we made a bundle selling the locations of worlds, "requiring" artefacts, setting up colonies of our own and ****ing up pirates.
