A brief history of the hybridization program

What star systems do the Yahyel and Essassani come from? Also, did they once look like greys but then mixed our DNA with theirs (is their any connections between the two)? What caused their people to become spiritually advanced and the Greys to become so malevolent (except for some Zeta Reticulans)? Something is compelling me to learn more about both of their civilizations.

Yahyel and Sassani are both created by human hybridization project recently. They were moved to other timeline incubated as a civilization there and then Yahyel is brought back to our timeline, 4th dimension. I believe Yahyel and Sassani are mostly ensouled by Grey souls, but I am not sure. I know some of human souls also incarnate in them.  Sassani civilization is few hundred years in the future. They come here only for special missions. Yahyel civilization is now in our timeline, 4th dimension.

Sassani’s star is said to be not in our reality, but it is not far from Sirius.

Yahyel keep their location secret.

Yahyel is said to be diverse having a wide range of hybrids with different proportions of human and Grey genomes. Other races are mixed in too but in smaller proportion. (Humans are also related to Greys, Greys are humans from an alternate timeline who destroyed their genetics in a war and then redesigned themselves to be peaceful and to live on ships.

What caused their people to become spiritually advanced and the Greys to become so malevolent (except for some Zeta Reticulans)?

The Greys actually were not malevolent. They were tricked and confused. They didn’t consider their actions malevolent. They acted out of sense of self-preservation. They were dying as a specie because of the problem in genetics and borrowed our DNA to resurrect their species. The Yahyel and Sassani are the result of this resurrection. The Greys infused their genomes with ours and this way were able to continue their existence. The way they were doing their Hybridization Program was very detached initially, and they were cooperating with Orions at the beginning. Later they became more sophisticated and separated from Orions. So in general, the Greys are not malevolent, they were harming people our of ignorance, but that is corrected by this time.
