I'm a reallyreally Bigshot of the abyss; why would I let Bugboy have it all??
I wouldn't!
While his back is turned and the worldwound is syphoning his forces I would attack the "wardstones" in his abyssal realm that opened and are powering the worldwound. Cutting off the return of these forces.
Throwing my own troops into conquering more of the abyss and capturing the resources there.
I will of course be supported by great and pwerful gods of good who want the worldwound closed..meaning Solars, Planetars and Epic Mortals will be using my abyssal realm to access the tagets.
...just an idea...lol
And who says the abyssal big guns are limitless? Would anyone keep sending their best defenders far fromthe seat of power when they're surrounded by dangers?
