So i am Gamemaster of an RPG, the location where the Party is, for the last few months, is a dyson Sphere.

Now i would like to let them go anoter place. So i need to destroy it on the best possible Way: I thought some nice Metorids.

So my Question is: How many Metroids do i need to shoot, and how big do they need to be, to Effectivly destroy all the hability of a Dyson Spehere? How would the Scrap of the Sphere react if the struckture is out of balance? Would the whole stuff just wobble around like waves on a Watersurface? Also - how could i explain somthing like that, so it sounds possible.

"A bing meteorid just appeard on the screen" - seems to be to easy for a civilisation that made an Struckture that is bigger than a Sun.

I would like to let them screen the scrap pieces in a later advanture but not if that sounds to artificial.

To The Sphere: From the sun to the outer layers

1. Habitable Zone: citys, agra farms, places
2. Support Zone: Electrics, water supply first Struckture level
3. Main Struckture: the other Struckture levels where everything is build on.
4. Spaceports and Cargo System: An infrastructure on the outdside where Spaceships can be dock and a network of "Trains" transport Cargo
5. Shield pylones: For shielding the whole Thing against little Meteorids and Ships.

I described the hull of the Sphere about 200 - 500 meters thick (according on what place of the sphere the Players were).
