Quor'toth

Quor'toth, the darkest of the dark worlds, is a hell dimension that can be accessed only through tearing the very fabric of reality and not via a regular portal, like Pylea or other dimensions.

Sahjhan opened the portal, thus forcing Daniel Holtz to jump into the portal with baby Connor. Connor grew up in Quar'toth thinking of Daniel Holtz as his father, who taught him how to hunt and hate his biological father.

Sluks, an indigenous creature to Quar'toth, were what led Connor to find the fissure out of the hell dimension.
