The X-Wormhole Legend

X-Wormholes are unlike any other rift or wormhole. It is a type of wormhole that can only open up during the X-Event. The X-Wormholes lead to a separate dimension that is entirely uninhabitable by humans, and the creatures that inhabit this dimension are extremely dangerous! These creatures have killer instincts, and whenever they are introduced to a new ecosystem, they seek to kill and destroy.
