No im pretty sure that Darth Plagueous was Palpatines master. But the real question is did Palpatine (or possilbe Plagueous) create Anakin from the Midichlorians seeing as in Episode I it is said he was 'born from the midichlorians themselves' or some such bs like that. and that he 'has no father'. So basically what are peoples thoughts on this, did Palps manipulate the midichlorians to 'father' Anakin or was this done by his master before hand. or am i just reading too much into the comment.
