This egg is a living paradox. One side is cold enough for ice crystals to form, yet the other side is hot enough to see heat shimmers rise from it. As the Icenyro inside grows the egg will undergo changes. At times the ice crystals will dominate, while other times the heat melts away almost all the ice. No side ever disappears completely during this process. As the egg nears hatching the two extremes will become balanced, each occupying exactly half of the egg.
The Icenyro possesses a very unique dual nature that expresses itself as it grows. When an Icenyro hatches it exhibits a strong affinity to ice. As it grows the ice affinity wanes and the fire portion of its nature begins to gain in strength. An adolescent Icenyro is balanced between the two sides of its nature, as evidenced by its eye color. The adult Icenyro is as strong in its affinity for fire as it once was for ice. At all stages the Icenyro possesses some small ice and fire magics. The magics for the strong affinity are the easiest to use, while the magics for the weak affinity are difficult and tiring to use. This means that adolescent Icenyro have a difficult time using these magics as their affinities are balanced. Very rarely an Icenyro is hatched who has its affinities swapped. These individuals are treasured and grow to become shamans of their clans.
