The night grew deeper, and the firelight in the tent became a bit dim. The Guard Commander, Ecatl, stood by, watching His Highness in deep thought at the desk, and called over a guard, whispering a few instructions. A moment later, someone brought over a birch candle.
The so-called birch candle is a candle made from rolled birch bark. Of course, other flammable barks can be used, but they are more troublesome than birch and usually need to be steamed first. In the Celestial Empire, this kind of candle belongs to ancient candles, appearing around the Han and Tang dynasties, and only entering common households during the Song Dynasty. For the nobility of the Alliance, they also have an equally ancient lighting method, splitting pine wood into thin strips and lighting it for illumination, known in the Celestial Empire as "torch".
