Rumble King's Confrontation

Military action

The Knights of the Golden Order used their considerable powers to grow to the size of mountains in order to faced off against the titanic entity known as the Rumble King. During the battle, their blood fell upon the mountains of the Spider Caldara and stained the stones permanently red (or black in the areas where Erithien Darkmoon's necrotic blood was spilt). The Rumble King was driven back to his Plane of Earth. 

In the battle, the Cropolis and Boiling Sea were exposed to the sky, the underdarks where the two places lay now accessible from the surface.
