I'm in the process of discovering how to add assassins in my mod. Essentially I want them to work as thug gangs do when you steal something in default Skyrim. You know those thugs that sometimes show up to assassinate you for being too grabby.

What I'm aiming to do is create assassins that are hunting the player when they have a specific quest. In this case it's my main vampire quest. Basically, this means that while the player is a vampire certain NPCs or groups of certain NPCS will show up randomly during play to try and kill the player for being a vampire.

I have no idea how to do this. Any help would be great. Thanks.

Use my http://www.creationkit.com/Creating_Custom_Couriersetup...but leave the aggressive AI on the baddies and launch them in groups instead of singly.

This looks very interesting thank you Red.
