In the brightly lit study, there stood a unique lamp submerged in water.
It was not made of "green fire" as its fuel, the smokeless lamp... Indeed, the light was very bright, but by the standards of a study, it was excessively glaring, which could easily damage one's eyesight.
After all, the Dwellers of the Depths are very sensitive to light.
With money, leisure, status, and technology—Naifertali had very high standards for her quality of life.
The walls and curtains of her study were made of furniture from the amalgamation of night-blooming flowers and secret oils. This material had an extremely high rate of light absorption; even at noon, it could keep the study free of sunlight. Conversely, it prevented light from the study from shining through the curtains, thus safeguarding her privacy.
To soundproof the room, another special ointment had to be applied.
