So every other DM quest seems to start with a tremor of some kind. Occasionally I'll see a quest pop up and crack a joke about it not having a tremor this time, only to realize I've spoken too soon.
Now, many people have made the argument that Dunwarren is geologically unstable. But these tremors never seem to be of a natural geological nature. Instead it's almost always something minor.
I could ask you guys to stop, but I have something better in mind. [COLOR="Red"]Add in a script that causes regions to shake periodically.[/COLOR] Maybe throw in a little scripted message about where the shaking came from. I just want some justification for the massive amounts of shaking because it happens so often in DM quests that it's just a joke to me now. You would think most of it would at least be natural.
The underdark does have very common tremors and earthquakes, bear in mind, as the caverns are very regularly shifting, collapsing, opening, and grinding against eachother :) Grumbar's whole concept of unchanging stone is thrown out the window.
