Prison liner escorts, can be done in all houses with lawfuls and unlawfuls logging to either protect or take out the liner. Maybe bump the price of (event?)prisoners so that if the liner goes down both sides can try to 'salvage' some significant profits by selling at prisons or unlawful bases.
NPC invasion events, oldie but a goodie. Be it Nomad, Cultist or maybe even house forces in a border skirmish that doesn't escalate into war.
A twist on the terrorist one; a suspected infected ship is heading to the location of a political target, local intelligence factions catch wind, declare it a criminal vessel and try to intercept.
Some spontaneous events playing into whatever story is currently doing would be nice as well, if only to keep the region populated;
The Insurgency tries to protect evacuation ships while the Navy tries to take them down
Luxery Liner Barbados gets accused of harboring Insurgency staff and must try to smuggle x amount of event commodity off the station before the event is over or risk getting caught (maybe more suited for a 'proper' event given duration)
Stuff seems to be planned to go down in the Omicrons as well but little actually reflects it currently, some extra Nomad based events in Minor, or conflict between the Corsairs and Outcasts would go a long way.
