Though their origin is still not understood, the devastation the swarms of these creatures can cause within moments of their coming is unprecedented, making them one of the universe's many serious threats. Despite intense research into the matter, the cause behind the vicious energy fluctuations in Xholes and Wormholes is still not understood, and unfortunately there is still no way to predict when these attacks will occur.
