——Salvatore certainly knew.
The first Tower Master of Heath Tower of Black was the "Flame Pilferer" Prometheus.
In the endless desert, the most dangerous thing was not the scorching sun.
It was the boundless night that descended upon the land.
That living desert would consume those within it come nightfall. In other words... anyone who lost their "light" in the desert would be swallowed up by the sand at their feet.
Therefore, to traverse that endless desert, one needed sufficient torchlight and... fuel.
The most challenging aspect was the fuel.
Because ordinary flames could not illuminate far in that desert. The darkness there felt almost tangible, heavy.
To solve this dilemma of darkness, an elf named Prometheus chose to become a "Flame Pilferer."
He stole the sun's "Third Dawn."
——Which was the "Eternal and Unrelenting Bright Flame."
