I've got a player who is entirely new to the 40k universe, but she's interested in playing as an Inquisitor (through some house rules we're using).
Any suggestions on where to point her to learn more about inquisitors? I know that there are a lot of great novels about inquisitors, but I'm looking for just some simple wiki pages and such that would give her a good overview, without being too much.

Thanks!

Lexicanum. Dan Abnett Eisenhorn/Ravenor/Pairah series. Dark Heresy 1 and 2 edition books. Inquisitor game.

You might also want to search YouTube; I know there were at one time a number of 40K videos which gave simple and succinct explanations on a number of topics.
