The Players
There are three PCs in our group. I had them fully roll up two random characters each and from the total six sought out those three that would complement each others' skills. I really enjoy the randomness of character generation in Warhammer's systems as it is like life; you cannot choose what you get and have to make best with what you got.

And if any should die, there is a back-up character already rolled up waiting to go in the wings that they've invested an hour in.
