Born from Braelith's first strategic victory, when the pyromancer discovered that controlling temperature differentials could shatter stone faster than direct flame. This revelation transformed random wildfire into calculated thermal warfare, creating the Thermal Dominus as the embodiment of heat weaponized through scientific precision. The entity emerged when Braelith realized that true dominion came not from burning everything, but from controlling the very concept of thermal energy itself.

Manifests as a humanoid figure wreathed in precisely controlled thermal distortions, with temperature gradients visible as shimmering air currents around its form. Its presence causes metal to expand and contract in calculated patterns, while nearby surfaces display exact temperature readings in glowing numerals. The entity radiates measured heat that can be focused into devastating thermal lances or dispersed into area-denial fields. Its core burns with the steady intensity of a forge rather than the wild flicker of open flame.

Serves as Ember Dominion's strategic thermal warfare specialist, using precise temperature control to weaken enemy fortifications and create tactical advantages through environmental manipulation. Commands respect through demonstration of superior thermal mastery, proving that calculated destruction surpasses chaotic burning in achieving lasting conquest.
