Frostgrave - Nullmen

Nullmen are infrequently encountered and only poorly understood. They do not fit well into any traditional category and are certainly not undead, demons, constructs, or natural animals. In terms of appearance, they are nearly featureless humanoids that shine with a slight, unearthly, grey light. There is no sign of intelligence in these creatures. They never try to communicate, and if there is any purpose to their movements, it has never been determined. Among wizards they are loathed for their complete immunity to magic.
