What does your inner world look like?
I'm not quite sure I understand what answer you're looking for. I thought the citadel was how you choose to react, your inner fortress against the outside world. Like a sort of meditative detachment.
I'm not trying to be dense, I'm honestly a bit confused by the question. Are you asking how I see the world? Are you asking what I think about most? Are you asking about my fantasies and dreams? Are you asking what the mood is inside? Are you asking me to imagine my mind metaphorically as a physical place and describe it?
That reminds me of
The Fall of the House of Usher. Some believe it's about the mind.
I suppose I can relate to that a bit. Not that I remember anything particular about that story but it is Gothic literature and like most Gothic literature it reaches for the "sublime". How do I describe sublime... it means to take enjoyment of something in a visceral way. Seeing beauty in things that are imperfect and sometimes even frightening. Enjoying the details of life that perhaps aren't often looked at. Gothic Literature is about creating a detailed setting, a strong atmosphere, and a story that isn't very pretty.
In that, I have no castle. I have a large old wooden house in the woods.
The place would have crooked trees fighting for the sky. The night's would have a big yellow moon and the days would be covered in overcast. The animals would be mostly quiet and observatory, hanging around the house lazily and having been there forever. There would be an ugly chained dog watching every step you make and chickens scratching around in the dirt. There would be flighty, tweeting birds, cardinals and sparrows.
If you listened closely, you'd hear the bugs rustling in the leaves, grass, and dirt. Not really a comforting noise, but not too unpleasant. Like the feeling of being watched but for just the briefest moment.
The house would be old and well developed. Large but not so big as to called a mansion. Never threatening to crumble despite it's age and uncared for state. Perhaps it gets cleaned up sometimes, Perhaps a few things get repaired.
But the plants keep vining inside and the front door never closes. The walls are always faded or dirty, with hidden details waiting to be found underneath.
It would feel like an adventure and an identity all of it's own. Walking through the house and being filled up with it's presence.
And at night unseen creatures would scream in the forest, their noises growing closer until your eyes leak and your bones shake. The trees shivering as the screams grow louder. The bushes begin to rattle far too close and you unfocus your eyes too afraid to see the reflective eyes shining wide and sinister, looking at you.
