Underworld Mod.
You've got 2 pirate starts there.
1 is you're Onesimos Loke's grandson I think (Loke is the guy Kanta betrayed to become pirate king). You've found grandpa's derelict infamous & unique Infernal Battlewagon capital ship, and can upgrade it during the course of the campaign to remove the massive amount of D-mods it starts off with while also adding on fighter wings, massive super-large weapons, etc. The con is that you start off with everyone hating you, and you've got to spend time building up relations with every other faction to even be able to dock on their bases. Expect to spend your first few cycles relying on independent planets keeping you supplied until you can do enough system bounties to get back to neutral with a few of the major factions.
2 is you're well connected to an elite TT-backed pirate faction that basically goes around extorting merchants, demanding credits, supplies or specific weapons/LPCs in order to avoid a fight. They're an interesting "faction", basically the remnant variant of pirates.
