I am wanting to recreate my D&D setting, the Kingdom of Deaegg, in Divinity. I figured the best way to do so was to create levels for each of the towns, cities, villages, landmarks, etc. which can be used in GM Mode. Along with these levels, I wanted to include all of the important NPCs that exist in my setting. To do so, should I add NPCs to the level in the Editor, or should I create NPCs to be added to the level within GM Mode during campaign preparation?
