|Grean the Time Warrior.|
Within the Exode Trilogy, I use "thon" as a pronoun to refer to characters who are neither male or female.
I had originally imagined that the Kac'hin might function efficiently as a type of communications interface between humans and the Huaoshy, but it turns out that the Kac'hin can only achieve limited access to the Sedronic Domain.
Grean grew up believing that Delpha was thons twin. A close personal relationship between Grean and Delpha was important because Delpha must function as Grean's bimanoid interface with the Huaoshy.
|Ekcolir and Trysta|
Grean became the main foot soldier for the Huaoshy in the Time War. On the other side of the battle was Trysta. When Trysta first became aware of Grean, she considered Grean as her enemy: an alien invader of Earth. Ekcolir was specifically designed and constructed to break down Trysta's resistance to the idea of collaborating with Grean.
Eventually Ekcolir was able to convince Trysta that it was possible to reach a negotiated settlement with Grean that would end the Time War. I'm still uncertain about the exact terms of the Tryst-Grean Pact.
