Archon

The Archons are living constructs of divine nature created by the Ancients. The methods used to create them were mostly lost with the collapse of the Ancient society. Very few Archons remain. Most have faulty memories from their age. All Archons were infused with a soul after construction and are powered by divine "god-energy" released from the Mobius Archive every 25 days.
The modern day Soulbound race is based on some of the knowledge & theories used to create Archons (but based on nechromancy or pure-technology).
