The eldest is Zahhak (or any derivative spelling) from persia, from what I know. Persia at one point  in the distant past bordered with the south-east Carpatian mountais from where the slavs traveled  where they are living today. I found mentions of possible older myths but unfortunately, they lack the written down form. Hence I have Zahhak, but spelled Dahhak as father, Aži Dahaka the evil twin, and Aždaja as his protector acting sister. There was a castle connected to the legend, but I don't know the details, but it's odd we have the word Zamak meaning something akin to a fortified castle today.

Edit: That way I have the full circle myth included in my worldbuilding as I have all three 'major players' even if they were once a single concept basically.
