The [ENVOY], or former envoys who once delivered messages from the Firstborn to the people of Eveden, have gone into hiding and now live among the citizens of various factions on Eveden. This happened after the end of the Machina War when the Firstborn vanished from Eveden. Their goal is to record all events occurring on the planet, waiting for the day when Adam and Eve will return. Today, they all have primary occupations to sustain themselves on this planet, but few know their true origins. This is the story of the encounter between the pioneering envoys and the new blood that will strengthen the organization even further.
