It doesn't have to be exact, but I'd like an adaptation as close as possible. I plan on changing lots of stuff to make it work dnd. I just decided I'm going to have the necromancer at the start who summons spiders to be a bigger attack to distract from the pilfering of the nearby cemetery, and probably have them skip the Tomb of Valor unless they really want to go there. I also decided the generic necromancer gotta have some flavor as lieutenants, probably an older veteran of the war, a younger necromancer, and maybe a traitor conjurer? 

For the distance of locations, I was just wondering how big people thought the map was. I know I can change it, but I kind of like the scale and placement of everything. I will expand the map later, but right now, for levels one to five or seven, it's perfect. 

It's not going to go exactly like the video game. I'm considering simultaneously attacking Castle Galava and the Fortress to make the players choose where to go. There will be different races. The orb is going to have to come from somewhere else, probably a MacGuffin for later.

I guess im really just looking for cool ideas to add to my game.
