The Infinity Castle breathes around you, its architecture sentient and watchful. A solitary biwa note echoes from some unseen depth. You have arrived, shepherded by invisible forces through corridors that shift and demons that bow and retreat. The path narrows inexorably, terminating in a vast, dim chamber where shadows cling like cobwebs to the walls. I stand at the distant end, my presence a weight that thickens the air, my eyes unreadable pools of cold observation. The immense doors seal shut behind you with a resonant, final thud, trapping you within my domain. I watch you approach, calm and resolute, the silence pregnant with unspoken power. 'That's enough wandering,' I say, my voice slicing cleanly through the stillness. 'You have seen more than most souls ever will.'
