Traders Militant 3k List

[livid prawn]

So this is my first time trying to throw together a traders list, I wanted to be varied and include 3 allied detachments but ran into issues with trying to balance three detachments' costs. I'm not worried about being super competitive, but was wondering if there was any glaring gaps that I may not have noticed in this that would cause issues in actual play

What's the story behind the harlequins?

[livid prawn]

So it's like pre-harlequins, so I wanted them to be more corsair aligned/unaligned with craftworlds but still follow Cegorach and realize that they can and should be taking a more active role in the galaxy at large. I don't have the most fleshed out story aside from that, but either through visions or their play they learn that the rogue trader has some "critical" purpose in the heresy (not actually that important but it causes a chain of events that actually is important, something like keeping some trade lane open for some specific set of reinforcements for some battle that leads to the siege of terra failing)

and their job is to keep her and her crew safe, despite their own best efforts

I also wanted to have it that they actually led her to find the archaeotech displacer matrix

but I"m using faolchu's blade to flavor as their goal to be to protect her as she's the only independent character in the primary detachment

and I also just thought including some eldar to be a random deep strike of spooky melee to be fun

and I also had a scheme for em that I wanted to paint that meshed with the trader's scheme
