CRACKLE!
The queen looked back, sensing a faint disturbance in the forces. "What was that?" She gasped. The dark void around her quaked, blowing like a breeze.
The elf goddess sighed, "This place is isolated from the outer world. It's a lone demi-plane in the infinite void of the astral plane." She lifted her hand, pointing behind the queen.
"That void brat's natural habitat is the astral plane. His magic is slowly digging its way, and soon he will reach us." The goddess flicked her finger, causing the world tree behind her to quake.
The branches crackled, slowly sinking into the ground as the leaves blew away, leaving a faint smell of lemon.
"It can't be. This place is protected by you. How could Arad jump in?" The queen gasped. She is in the presence of a goddess. A mortal shouldn't be able to enter.
The astral plane is a limitless void. The gods see it as a waste to leave such space unused, especially since it has nothing their presence can crush.
