Well, there are six Ilari that are guardians that help you. There are also neutral Ilari, fallen Ilari, and dark Ilari. The neutral ones you tend to meet in caves, and you never know quite who you're talking to on the other end of those. The fallen ones aren't really in the game in a way that you can encounter at the moment, but the dark Ilari's influence can be seen in The Deep (though you don't see them directly, or even their stones).
