Megachidna, the home star of the Ta'Elans, is a Thionic Hypergiant Star. Stars like this can shine indefinitely so long as they remain "fed" by the energy of other nearby stars.

Thion Technology refers to the technologies and science surrounding a mysterious phenomenon discovered by the Ta'Elans. Early on in their history, they discovered a way to turn matter or energy into an intermediate state, which acts as both matter and energy, but also possess qualities not observed in either. They had discovered the Thion Particle, also referred to as Thionic Wave Matter, and it is one of the critical discoveries that would lead to the Ta'Elans becoming the most powerful civilization in the known universe.
