In the book "Born of the Night" by Sherrilyn Kenyon, the character Syn is depicted as having a brain disorder that leads him to frequently tell lies. This condition complicates his interactions with others and raises challenges in building trust. His tendency to fabricate stories means that much of what he says can be doubted, encouraging those around him to be cautious.

Nykyrian, another character in the story, advises others to ignore Syn's lies, highlighting the difficulties in communication and relationship dynamics affected by such a disorder. This suggestion emphasizes the need for patience and understanding in dealing with Syn, as his condition is not a reflection of his true self but rather a result of his struggling mind.
