The Book of Sith is good reading as well! Sidious is inspired by Bane as wish to accomplish what no other Sith could... Defeat the Jedi Scum and raise a Sith Empire. Though he planned on doing away with Bane's rule of two by ruling by himself.
The book of Sith hints that Plaqiues actually created Vader as a false prophecy. And that Sidious knew this! And I don't think Sidious was much of a Sith Lord.... More of a politician with knowledge of the force. Bane was the real deal!
