With a steady breath, Instructor Lira muttered some chants, her voice low and rhythmic:
"Ignis pura, flamma constans, unifica essentia."
The students saw nothing, no sparks nor light, but within the sealed vessel, a blue flame erupted that swirled with intensity.
It enveloped the ingredients, coursing through them with aggressiveness.
Lira's hands moved deftly over the cauldron, her fingers tracing invisible patterns as she controlled the flame's ferocity.
Occasionally, she whispered another chant, "Tempera ignis," to lower the heat, or "Cresce flamma," to intensify it.
The room remained silent as the students were transfixed by her focus.
Beads of sweat glistened on her brow, her eyes closed as she muttered incantations, each one syncing with the flame.
The process stretched on and the air grew heavy with the sharp, herbal scent of fusing ingredients.
