According to Wikipedia:
Rassilon is a fictional character in the British science fiction television series Doctor Who. In the backstory of the programme, he was the founder of Time Lord society on the planet Gallifrey.
Reading the Wikipedia entry I see that there’s quite a bit to this Rassilon character. I really need to watch more Dr. Who. Do I start at the very beginning with Season 1, or is there a particular season you suggest I start with?
