With a (somewhat) reasonable cause for Mara to stay in the Dreaming City, that still doesn’t answer the question of where exactly she is in the City? Judging by the decor of her Court, I’d say the Mara retreated to the Chamber of Starlight. If you take a trip to the Lost Sector, you wouldn’t find anything close to Starlight (save for the sparkling amethyst, but that’s literally everywhere) and I think the reason for that is because that isn’t the actual Chamber. The actual Chamber is behind the enormous door at the uppermost right side of the room, which appears to be similar to the two doors located in Mara’s Court. The decals aren’t exactly the same for the doors, but the positioning of the Chamber os Starlight door on the map is rather close a drop off, around where the Item patrol Corsair in the Divalian Mist stands, meaning it likely goes down and not straight out, likely putting the actual Chamber (and potentially the Queen’s Court) deep down beneath the Silver Sea. Possibly below the entirety of the Dreaming City, where it would peak out into Space the way it does in the Queen’s Court. The Starlight part of the name is self explanatory, with the nebula and all that stars being directly behind Mara’s Throne and in context of royalty, a Chamber is usually a section of a Monarch’s estate that they could retire to. In essence, this would be the equivalent of Mara locking herself away in the tallest tower. Kind of like Rapunzel, and every three weeks, she’ll let down her hair to let her Prince(ss) Guardian-charming know just how little she appreciates their work. I’m getting off point. With the idea of Mara remaining in the Dreaming City, there’s still the problem that the place isn’t safe. The first thing Mara said when she got back was that she couldn’t stay there. So what’s the deal then, how could she stay if she’s not safe? Well the short of it is that she’s undetectable down there, and could quite possibly be off the grid in a dimensional sense. When the Ghost was first presented with the location to the Dreaming City, he said that it’s coordinates shouldn’t exist, suggesting that 3d space there doesn’t abide by normal rules of physics, specifically strung in a way to not be detectable, both visually and logically. And this is saying a lot in a universe where Dimensional Bleed is so rampant, the Guardian was able to walk into the Black Garden through a broken wall in a Martian subway, while still abiding by the rules of normal reality. Not to mention the fact that the Dreaming City brushes up incredibly close to the Ascendant Realm, to the point that the seam between realities will let loose, allowing free passage between the two worlds. I think something similar is happening in the Chamber of Starlight, in such a way that it camouflage the location from any possible rival Scheming-Queens as well as confusing the ever loving hell out of the Guardian’s Ghost when they try to figure out where they are. What I’m trying to say is the fabric of reality in the Dreaming City has been tied into a gordian knot from all the geometric masquerading, time looping, paracausal shenaniganory and all around general demential elbow rubbing. And at the center of that knot of nonsensicality, in the bowels of the Chamber of Starlight, is the Queen’s Court, with Mara sat daintily on her throne. As an overview, Mara came to the Dreaming City, saw it was in ruins and so she retreats to the last place she can hide away while staying close enough to keep an eye on things. She only communicates through the Oracle engine to try and keep her location a secret because having the Guardian come to her via the passage in the Chamber of Starlight every time they have a report to deliver would lead the Hive straight to her. So even though the Oracle can send the Guardian to anywhere in existence, it’s only taking them below the disc the Dreaming City rests on, then sends them back with just a normal short range teleporter. That Nebula the Court looks out to will convince the Guardian they’re off in some distant pocket of reality, Petra doesn’t have the will to go asking any more questions after Mara gave her her orders when she first arrived in the Dreaming City out of fear that her asking will be seen as her not believing in her Queen, the Techeuns are too afraid to reach out to Mara and find out where she is in the case that they’re taken again, and her Court is so well hidden by the reality in the Dreaming City that Mara doesn’t have to worry about the Taken finding their way to her, even on accident. So there’s literally no way that anyone could figure out where she’s been coped up for all this entire time. Except for… oh I don’t know, some handsome young Kell with exceptionally long arms to reach with. Or not. Anyway, that’s my two glimmer on the matter. If you made it through relatively understanding what I was trying to say, I thank you for reading that mess. Pt 1; https://www.bungie.net/en/Forums/Post/250610232?sort=0&page=0
