I think the
Nocturnal Knives spokesperson is just a pathological liar.
Pathological lying
Pathological lying is a behavior of habitual or compulsive lying.[1][2] It was first described in the medical literature in 1891 by Anton Delbrueck.[2] Although it is a controversial topic,[2] pathological lying has been defined as
"falsification entirely disproportionate to any discernible end in view, may be extensive and very complicated, and may manifest over a period of years or even a lifetime".[1] The individual may be aware they are lying, or may believe they are telling the truth. Sometimes however, the individual may be lying to make their life seem more exciting when in reality they believe their life is unpleasant or boring.
