Yin and Yang.
The thought appeared in Michael's mind as he looked between the twins.
The concept itself was ancient and incredibly broad. Yin and Yang were not simply opposites.
They represented two contrasting forces that existed together, restrained each other, and in many cases completed one another.
Yang was often associated with activity, heat, strength, vitality, expansion, and the physical.
Yin leaned toward stillness, cold, spirit, energy, perception, internal force, and the immaterial.
The exact meaning changed depending on the system using it, but the principle was usually similar.
Opposites. Yet connected. Separate. Yet complementary.
Looking at Cael and Miki, Michael could see that idea almost perfectly reflected in them.
Cael had black hair and represented Yang, yet his ability sacrificed mana to strengthen the body.
Miki had white hair and represented Yin, yet her ability did the opposite, sacrificing physical vitality to strengthen mana and magical output.
