The real Vali and Illyinni were fighting alongside the weaker experts, fending off the remainder of the weaker Cavern and the Divine one. It was one nasty bastard. Its features were very human-like and feminine. Its size, ten times as large as the average human, already made it formidable, but its Divine status made this trait especially troublesome to deal with.
Illyinni and Vali had nearly died to it six times. Well, the former would have, if not the additional clone Vali had stick with her to heal her instantaneously using Cellular Supremacy.
The great Cavern pointed below at some of the weaker experts around and darkness lathered ten of them, turning them into shadows planted on the dirt at once. Indeed, it was an uncanny ability.
The Cavern as a race had an affinity for darkness that had once stumped even Festos.
Oddly though, the victims of this trick it used, vanished; indeed, the shadows disappeared from the dirt almost immediately.
