Outside the barrier maintained by a series of "Boundary Stele" at the edge region of Boundary Land, lies the physical border of this space-time convergence—beyond the hazy light curtain and large swathes of desolate, dim terrain, at the extreme distance visible from the last outpost set up by the Special Service Bureau, are vast stretches of fragmented, floating island-like landmasses hovering in semi-chaotic air.
Aurora-like streams of light flow among the countless shattered floating islands, with small space stabilization devices visible everywhere. The starlight from the external universe occasionally penetrates the gaps randomly appearing between the floating islands, casting reflections over those islands, whether desolate, lush, or illusion-like.
On one of these islands, whose material structure and existence are relatively stable, stands an old mansion shrouded in a mysterious aura, surrounded by a flourishing garden.
