Ersham

Ersham(?), an old Illyrian god and a personification of the old capital Ecbatana. He's still worshipped in certain parts of the world, but for the most parts his role has been replaced by the goddess Ys.

Some consider him to be the father of Ys, though most of Ys' birth myths have her being created with the bones of a much older planet. 

In some myths, Ys and Kuja are created from one of his ribs, which was broken in half.

He symbolizes earth, sky, sun, and water alike. A god of existence in a way.

The goddess Nefas originates from the same era as him... she's one of the few very old gods still worshipped within Illyria, though it's in large part due to the fact that Nefas is the city-goddess of Elaia.

( Also considering Arsama or Mahdjoub or just Ecbatana as names 😭 )

( Might make him a trans masc king. )
