Violet thunder roared in the sky above them, sending lightning crackling haphazardly across the once-peaceful veil of night.
The lightning was unlike anything any of them had ever witnessed, nor did the lightning follow the natural patterns they had grown used to seeing during ordinary storms.
It weaved through the darkness like serpents of pure malevolence, like countless electric snakes momentarily sprawling across the night sky as if the non-living display had some sort of predatory intent.
The portal that had been opening gradually suddenly expanded with astronomical violence.
The growth was so rapid and massive that a small town could fit through it. The sight was both mesmerizing in its own way and utterly terrifying.
Through the violet swirling vortex of the portal, they could see nothing, as they were unable to see through it, making them tense up increasingly.
