Custom Guard Dialogue/Creation Kit Help

[SemprusGalligan]

I'm working on a large and ambitious mod that brings The Shivering Isles back to Skyrim. In a sequel format.

I wish to have the Golden Saints and Dark Seducers with their own dialogue, of course.
And to replicate what happens when you attack Sheogorath.

I know about crime factions and the like, but I need to know how to make the dialogues and scripts.

Can someone tell me how or at least link me to a good tutorial?

It would be GREATLY appreciated.
