Well I'm starting on a new area today called Dragon's Heart. I'm just starting but I wanted to give a rough idea of how things always start out when I do this.
I was thinking to myself over the last couple days... hmm you know, you never get to see Dragon battles in NWN2 much, and it's not because there aren't any Dragons, in fact there's 5 of them. I suspect it's because they are so high of level most modules aren't made for it.
I had been looking through the toolset trying to decide what I wanted for my second add on area. I knew one of them was going to be a Spider filled forest, but for the second one I kept asking myself what is it's theme going to be? It's going to be the place the Sky Pony tribe sends you for clues to the location of Claw Hollow... but... what is it once you get there?
Well putting all that togather I came up with an idea.
It was called Dragon's Heart...

Now obviously it's just starting, so... given the texturing in the pictures of my other stuff you can see how it's going to turn out. I'm, using the same texturing and forest look as in One Stone.

The Sky Pony Tribe calls this place Dragon's Heart, both for the shape of the valley and what lurks there. They tell you one of their trackers was lost there while attempting to track the Lycanthropes to Claw Hollow.
Well do you see all those little valleys? A Black Dragon named Ix'chidgit Monlaesus lets her Wyrmlings loose here to hunt and practice their skills on the local Troll population. Needless to say the Trolls are terrified of them. Now if Trolls weren't so stupid they'd probably ask you for help, but it's doubtful they could even communicate with you let alone ask for help. Besides, they're hungry too and would like nothing better than to have yo for dinner as well. So this Valley is going to be populated by Trolls and the Black Dragon Wyrmlings hunting them. The Wyrmlings will be on little patrol paths around the valley. And you'll most likely run into Trolls as well.
Here's the catch... if you kill too many of the Wyrmlings, Ix'chidgit is going to show up and start hunting YOU. Now, being Chaotic Evil she doesn't really give a damn about the Wyrmlings that much and figures if they aren't strong enough to survive it's their own fault for dying. But if she sniffs some stronger prey in the area... the game is on...
Given that the party will likely be 10th level at most... and that an Adult Black Dragon is 19th level... she's probably going to chew you up and spit you out faster than you can say boo. So if you don't run you're going to die unless you're really really good. It will be a fight you won't soon forget.
But you don't have to beat the Black Dragon to clear the area, all you have to do is make it out alive with the clue that is on the body of the Sky Pony tracker who was on the trail of Claw Hollow.
If you actually succeed though in killing Ix'chidgit, it will open up another area on the map... her lair.
