"Now," she said, tone shifting with precision, "let's talk about how elemental affinities are influenced by mana."
She paced slowly, eyes scanning the students.
"First, we need to understand how someone even possesses an affinity and why or just what even the hell it is? Why do some people have stronger control over fire, others over water or wind, and a few even possess rare dual affinities?"
She stopped and looked directly at the class.
"As with many other things, it's tied to your bloodline too. Inside your body are unique structures called elemental cells. These elemental cells, unique to every individual, are dormant until they come into contact with mana. Once activated by mana, these cells resonate with specific elemental energies present in the environment, creating a connection between the individual and their elemental affinity.
