I would home in to investigate a distant tsquare of pluto moon sun jupiter as being the underlying culprit.
mercury pisces is the carrier for divergent ability to synthesise information anyway, its also not a 12th house ability.
house systems are fluid because they dont characterise but focus on specifics arena. They give predisposition to seek certain features in a day to day life to present the characteristics as events. but they dont flavour character. And anyway pisces is a 12th house rulership by default.
your pattern from the description you express is all about power. the power to withhold, to demand, to master your environment just as you wish or disregard in totality. its your will, your way be done…or the highway.
its far too threatening, too dominating yet far too concentrated for anyine to disregard. whether you take part in any group or not is not actually important or necessary for the effects to be felt by anyone within regular contact be it even in vacinity. it doesnt need acknowledgement or even participation from you. proximity is sufficient. even the energy waves of you arriving …before even arrival…sets off forceful change reactions. This is why you as a person can be forgotten or not noticed, but effects are.
it might be that in a chart a whiff even at a distance, is good enough to cause integration and even by sign, as it seems to be effective …by your words. since your character is such as to hide and not disclose and even camouflage, its best for you to examine on your own.
so study the pattern. maybe it will bring you some peace through understanding and make you less resentful. There is a sextile from sun to uranus in Sag. it offers possible divergent, reinventive ability to bolster your sun….but give its all im fixed signs, it may be too little to sway all that fixety. at the end, what you want to believe, will be retained, irrespective.
