Hidden deep in the rear of Daiou Paresu is the doorway that leads to Caelum's quarters. Caelum's chambers are quite large with a large reinforced glass window residing in the ceiling of the room that filters in moonlight at the appropriate hours, and sometimes simply when the master of the room desires it. A sizable four-poster bed resides at the center of the room by the southern wall, perfectly placed to allow the glow of the moon's light to gently wash over it when the window above filters in light but not to such an extent that it may disrupt sleep or stave off the darkness. The bed is rather interesting, the bed spread is pure white as are most things in Hueco Mundo and Caelum's stronghold, but the cover that lies atop it appears mysteriously both a varying blue and obsidian black simultaneously. The pillow that rests at the top of the bed is pure black with a surprisingly attractive blue threading and trim that matches the color of his hair and, on rare occasion, eyes.
A dresser and lamp lies next to the bed on the southern wall next to the doorway that leads to the Demon's Nest. The doorway itself is obscured from view.

On the Eastern wall two large bookcases rest, filled to the brim with various reads, all of differing genre, which Caelum can sometimes be seen reading. A chair can be seen in varying locations, depending on where Caelum was last sitting or where it last best found his interest. A desk lies next to the bookshelves against the northern wall where papers can usually be found, sprawled over the surface with writing on various topics and often a book or two.
