Students of Unblinking Flame
The Students of the Unblinking Flame are monks, fighters, and other warriors, who are sent to one of three highest specialized schools on the Isle of Jalmeray. Each of these schools focuses on one element: the Untwisting Iron, the Unfolding Wind, or the Unblinking Flame. Upon entering a school, the warrior gains the title of Student of the appropriate order, and when they end their study, they become Master. Many titles come in between, but most often Student and Master is used.
Every school has its own specialization. The Students of the Unblinking Flame learn how to move as a spreading fire, adding bursts of fire to their attacks and transforming into a wildfire, scorching their enemies while rushing by them in a blazing inferno.
