That sounds like a command destroyer with a micro jump field generator jumped your ship 100km off the station. There are 4 command dessi, one for each faction. But all of them have to get within 5km of you to do it and there is an activation time. So if you know the game well enough you dock when you see a Magus Bifrost, Stork or Pontifex. You have to be within 300m of the station to dock so sometimes they will attempt to bump you out of docking range before they warp in the command destroyer. 100km is still within range of the station guns, so if they illegally attack you, the guns will attack the assailant, therefore even after the command destroyer has jumped you , if it warp scrambles your ship the station guns will kill destroy the destroyer pretty quickly. So they need a collection of other ships to actually stop you from just warping off at that point.
The point is this is how much thought has gone into killing you and the only reason they make the effort is because you brought a ship that will look good on their killboard.
What you have to understand about Eve is that everywhere outside of high sec is inhabited by psychopaths that kill for the sake of killing. It’s just a matter of them figuring out how to do it.
That’s not the whole story, sometimes they are territorial.
It’s like an eco system, gangs form, gangs grow, gangs recruit because the bigger gang can dominate and protect itself from other gangs. Thus they are quite keen for you to join them and if you intend to exist outside of high-sec then it’s not a bad idea.
As a lone unaligned pilot they don’t actually have any need to destroy your ship because you are not a significant threat. You might kill a ship or two but they plan to lose ships every day.
They say don’t fly a ship you can’t afford to lose, but if you PVP you need to be able to lose that ship every day. or every hour. because we are immortal, and most of the time there is zero intention of docking back up in one piece, it’s just a matter of how much destruction can be caused before yourself gets destroyed.
As a factional warfare player I am prepared to RP and not kill a venture that goes into low sec to experiment mining hedbergite but I’m a minority, most people will slaughter that without a second thought.
A rattlesnake in low sec. People aren’t going to assume you are on your own, unless they look at your killboard and see you lost a rattlesnake every day this week, then it’s Christmas turkey for the boys, get the chainsaw and your ship becomes a giant pinata.
