Astra

Energy of the Precursors
As of now little is know about Astra energy. It is an ancient form of energy used by the Precursors.

Astra also goes through a form of reuptake within the gods, in which they create Celestial Energy out of it.

Astra, Heros and Seraphim
Heros, now God of the Ancients, was once a Precursor who experimented with Astra energy. After viewing the diffrences between Astra energy used by the Precursors and Celestial energy used by the Gods, he sought to make a bieng capable of wielding both with ease. Through these experiments, he created Seraphim, composed entirely of Astra and Celestial energy. It was soon after this, Seraphim used his power to lead the Gods in a rebellion against the Precursors, and giving himself the title "God of Gods".
