Forlarren

Forlarren were a race of fey creatures that came about from devil corruption.

Abilities
Forlarrens were innately capable of casting spells and had some resistance to magic. Out of the spells that they knew, heat metal was most frequently used.

Personality
Due to their mixed fey–devil ancestry, all forlarren displayed a somewhat bipolar and temperamental personality. Their fey ancestry drove forlarren to act in ways seen as self-destructive and once they reached a breaking point through such behavior the diabolical side of their personality would assert itself.

Forlarren dominated by their diabolical mindset were known to be rather cunning, scheming, and vicious foes. They often sought to dominate or mislead weaker creatures. Once whatever diabolical schemes they had were foiled, a forlarren's fey nature would reassert dominance over their mind.

Sometimes killing an opponent could cause this shift in mental dominance, with the forlarren displaying great remorse for its actions and offer its services to the survivors as recompense. But eventually, their diabolical mindset would reassert itself and the forlarren would leave such a group, attacking them on sight the next time they met.

Combat
Forlarren were typically known to attack up close with their fists, claws, and in the case of armored opponents their signature heat metal spell. When they used this spell, forlarren were often quite difficult to separate from their armored victims. With some maintaining contact until either they or their victim was killed.

History
The exact origin of the forlarren was uncertain; there were two conflicting legends, though both agreed that a devil was involved in their conception. The first legend claimed that the forlarren were descended from the offspring of a good nymph enslaved to an unspecified type of greater devil.

The second story claimed that when the devils of Avernus mounted an expedition into the Feywild, the archduke Fierna tried to court an archfey, with hopes of seducing them into relinquishing their soul. Her efforts ultimately went nowhere, but a group of the lord's satyrs had become infatuated with her. She was unable to claim their souls, for they were bound to their archfey, but Fierna still desired some form of gain from her time spent on the lord. Thus, Fierna decided to corrupt the satyr with her infernal powers and transformed them into what became known as the forlarren.

Society
Within the Feywild, several heroic tragedies and ballads were written about forlarren. These depicted them as valiant figures, but whose diabolical personalities emerged at the most inopportune moments and led to treachery for their allies.

Homelands
Outside of the Feywild, forlarren were known to be found in the High Forest in the North.

Note
The description of the forlarren's ancestry and behavior in the 1-edition Fiend Folio notably bears a striking resemblance to "The Fiend," a creature from the first installment of the British gaming magazine White Dwarf's "Fiend Factory" feature.
