I just discovered this new (to me) blog that has a really nice explanation of the different factions and different masters in Malifaux. It's approx. a paragraph description each. This should make for a great reference to any beginner who wants to choose their first starter set.
Joel is also on twitter if you are interested: @Joel__Henry
PS> I'll certainly be adding this blog in the sidebar too, as it looks like there is a lot of great information on there. If anyone else has some blog recommendations in relation to Malifaux, please feel free to leave a comment so I can check them out.
