The Triangular Nuclear Loop basically is a body of plasma encased into an shell made both to preserve its form and protect it. In the case of the Reyvateils, their brains are the shells. The Loop also contains in each one of its hexagonal hinges (the hexagon-like structures in the vertices of the triangle) special Dynamic H-Waves that control the growth of the Reyvateil's body, and also, the Telomere that control their life spans. It wouldn't be an exaggeration to say that the Loop controls completely the life, growth and death of the Reyvateils.
