(Created just because I felt like it.)

If one were to somehow enter Nihil's realm without his or his family's permission, this is only some of the many unspeakable horrors they would face. These things also appear on worlds conquered by Nihil, as the Dark Realm was merged with them. Many of the creatures are humanoids, but make no mistake, they act just like any mindless bloodthirsty creature, but they also don't have names.

Note: One day, Nihil was told by his daughter Hershey that the creatures tried to kill her, and she told him she didn't have anything to ward off or see the creatures. So in order to keep his family safe from the creatures in his realm and allow them to see, Nihil created personal lanterns for each of them, with their own colors. Cinder and Scorch have orange lanterns, Emerald and Toxin have green lanterns, Salem and Reaper have red lanterns, and finally Neo has a pink and white lantern while Hershey has a pink and red lantern. These lanterns help the creatures know that they cannot attack them, not to mention the scent of their creator upon them will also deter them.
Note 2: The creatures will devour anything and everything that does not bare the taint of Nihil's corruption or is not made from the same darkness that they are made from. They will not only devour the flesh, but also the soul of their victims.
Note 3: On the conquered worlds, Nihil's loyal subjects are basked in darkness, allowing them to remain unharmed by the creatures that forever walk their lands. These creatures can easily sense a being that is of light or has pure intentions, being drawn to them like moths to a flame, as they want to devour this delicacy as soon as possible.
