Half-Fiends are creatures that possess both mortal and fiendish ancestry, typically resulting from the union of a fiend and a mortal. They often exhibit physical traits and abilities inherited from their fiendish parent, such as enhanced strength, darkvision, or resistance to certain types of damage. These beings often struggle with their dual nature, facing prejudice from both mortals and fiends. While some may embrace their fiendish heritage, others seek to distance themselves from it, leading to a variety of motivations and alignments among Half-Fiends in different narratives.
