World Of Darkness
"I'll take one last look at it, and I think later ... I will."
After looking at the map, the prominent places, some important NPCs, the nations that made up the world, among other things, I get to the most important detail, the main enemy of that campaign.
Currently I only had ready the final Boss of an incredible dungeon with a castle design, I also had some details ready such as the castle locations and the NPCs that would function as the Bosses of each zone.
At this time, he only had the final Boss character sheet ready, and he only had some initial concepts of what the Bosses in each zone would be like.
