This whole thread reminds me of Bloodbird and her amarrian colony in republic space. As long as it remains coherent, logical, structured, and with an OOC "gentlemen-agreement" behind, I do not se why I should screw with that.
First rule in roleplay : scenario before anything else, or no need to roleplay anymore, just play the game lile the average player.
For the record, I'm male. So is my oldest toon, though Jesmine is not.
Nit-picking aside, for this tread I'll share a bit of knowledge. I seriously don't think I'll ever get to the point where this is used IC or in any story of mine, anyhow.
Back when I were still writing out the basis for the story that my main toon was involved in, I involved several other players, among them Veron Daerth and Stitcher. The idea was originally to make an in-universe story to explain why my toon was gone for several months leading up to this point. Ofc, I could just have stated he was on a break, much like I was, but it was an excuse to write a story, and I took it.
Long story short, Veron and Stitcher both made wonderful pieces of the story, actually a chapter each, to describe their help towards my toon in this situation. I would write the rest and it would tie their contributions in with the overall plot.
All of this is gone and lost a long time ago now ofc, but at the time there were two things that defined my work from the viewpoint of our collaboration as players; the story would be believable from an IC, PF viewpoint and it would take part nearly entirely outside the confines of the game. Lots of actions on planets and other non-space locations. A few acts took place in space, mostly with myself, simply being at places I was supposed to be in relation to the story. There were none around who saw me in these places, but the idea was that, if they were and read my story later, they might recall seeing me there and go 'aah, so that's what he was doing there.' In-game action to back purely fictional action. Was not much else I could do, In-game.
Now, this story would also demand from the reader to accept that Capsuleers came from some other place originally, they were not born into their capsules in some beginner-station somewhere with a less-than-a-day record in their beginner school, and no places of origin or any parents etc.
Nearly everyone who call themselves role-players are forced to agree that all our toons have 'lives' and back stories besides our purely in-game activities. I for one will refuse to call anyone a 'role-player' who refuse to acknowledge that my toon was born and raised, SOMEWHERE by SOMEONE. And when I tell anyone IC about who they are/where where they lived etc, there is a very high chance they will believe me.
Granting that another toon was born by someone and came from somewhere, is not to hard to swallow or agree to. Few of us however, will give much if any credit to anyone claiming to be the Empress' genetic twin. This ties in with credibility of one's RP and stories; what is believable and plausible, and what is not.
I took great pains to ensure that my story, while somewhat 'hero tale' type, would be believable to any, if not all, readers. It even included a hopefully-credible solution to how one escapes CONCORD supervision to do things they would never allow an egger to do normally. My toon's 'suicide by ship self-destruct' was another 'IG' action based on this story-arc.
Right now, I am in fact selfish enough to wish I still had that work and could post a link here, I think it would have covered the issue at hand, quite well, though quite a lot of reading. Basically, I see no reason what-so-ever that Capsuleers and their closest friends/associates etc. can't have some degree of 'special' to them or some amount of power.
If Andreus ever told my toon IC his back-ground story, I would see no reason to doubt his words. Sure, it might actually come a day when CCP release a huge, thick, bible-like book about who, what, when, how, where etc. in New Eden, and it might even state perfectly that all of Intaki is ruled by purple brain-slugs, thus spectacularly destroying his explanation and claims about his family's dealings there.
Ofc, we all likely know this will never happen. And I'm not one for denying myself or anyone else creative freedom in a game THEY PAY A MONTHLY FEE to enjoy, the right to make up fluff as they go, just because CCP 'might' one day do something that will invalidate that. But of course, it's not really to much to ask that it's kept believable enough not to rub everyone else the wrong way.
Basically, if it's fluff that adds flavor to your toon without rubbing other toons in ways that is not, in lack of other words, polite, then I see little problem. If your quest to add fluff to your toon or explain actions or some such taken by your toons, screws another toon over or seriously breaks immersion, that's another factor. Sadly, these vary greatly.
