I was discussing Nex Alea with my friend and he brought up 40k Orcs, he said they'd love it. They probably go to the center and look for enough dakka.
After informing him that the center is just a rock, the first murder weapon, something clicked in my head as he asked what I thought would happen if they realized this.
>"Boss! Boss! I found enough dakka!"
>"No you dint you fookin grot!"
>"No boss! You don't understand! It's a rock!"
>"You fokkin wot!? That's fokkin dumb that is!"
>"But boss! The entire planet is a rock!"
>"…thas fokkin cunnin"
I propose, that enough dakka, is to attach jets to the planet, and fly it, defy gravity, defy the warp, and fire the planet at enemy ship and other enemy planets. Based on how gravity works a big enough planet would fuck with the gravity of everything around it. You would have a weapon that literally warps space.
