I was just playing Jedi Power Battles and thinking what a cool character Maul is, but mourning the fact that in TPM he got no depth or backstory like Darth Vader (like the rest of the characters in TPM). So is there anything worth mentioning, in the EU, that gives Maul a little meat? Maybe deepens the character a little, gives a backstory as to why he's so vicious? I understand there's a children's book and a comic series, but haven't heard if these are a waste of time or not (and I might feel a little more silly reading a kids' book, but will if it strengthens Maul's character).
