another question Esther (from mck) i saw people say she is not fictional and possibly a servant of hurrem/nurbanu/safiye is this true? also meleki (from mck) i also saw people say that she is not fictional either and betrayed kosem and aligned with turhan and that there were rumours that she and turhan were in a relationship is this true too?
Esther was not a servant but a Kira ( mediator between harem women and the outside world) they were not slaves in the harem. and yes she lived during Nurbanu's and Safiye's possibly even Hürrem's time. They were mostly jewish.
Here is the video I made about Meleki
