Originally, Lux thought that there wasn't a night and day cycle in Zangrila when he first arrived. But it didn't take long for this assumption of his to be corrected.
During the day, everything in the surroundings was void of any other color except for the color of red.
At night, everything became so dark that only the moonlight illuminated the surroundings. There were no stars in the sky, and the only thing that could be seen above was a white, full moon.
After finding out that there were countless ghosts in the city, the Half-Elf decided to take a stroll to clear his mind.
For some reason, the brother and sister ghosts followed behind him. They would always stay a dozen meters away from the Half-Elf as if following him was a fun thing to do.
Lux let them do what they wanted as he was busy thinking about a lot of things.
His friends who were in the Gate of Famine.
His inability to control Hecatoncheires.
