First things first. Is the Creation Kit based on C#? Only asking due to using visual studio, forming a code on there, test to see if it needs debugging, and then transfer the code onto the compiler of the CK. If based or friendly, then creating basic scripts will be easy.

Secondly, about the domain activiation. What I mean by that is if my first question is successful, on one of my quests I wish to create an advancement of a quest whenever the player is within that domain. Will triggerboxes be the approperiate use of activating and advancing the quest or is there something different?

Thanks in advance!
