I dunno what I see in Emps. I'm someone who struggles with social stuff and empathy so I suppose because the Emperor is different, I identify with him on a level that others don't.
It's fascinating to see how others view him. I would think he is somewhere between neutral and evil.
In any case, I would like an option that allows the githyanki to be free from Vlaakith, without someone needing to transform into a mind flayer.
