User blog:DragonsHaveMoustaches/Why did Gaius take Morgause to the High Priestesses?

Hello! This is the first time I'm writing a blog, but this has really been buggering me for quite a while.

Gaius often referred to the High Priestesses as being evil (e.g. he knew that they used the Fomorrah to control people's minds or that they created the Lamia).

So I don't understand why he took baby Morgause to the High Priestesses instead of taking her to the Druids or to someone/somewhere else. He should've known the Priestesses would teach Morgause dark magic and would turn her against Camelot. Did someone (Nimueh?) order him to? Did he believe she would've been safer there?

What are your thoughts about it? (I know Morgause's role in the story is supposed to be over, and I understand that she had to die in order for Morgana to become the main antagonist, but it's a shame the character will always be shrouded in mystery).

I'm sorry if this question has been asked before!
