Homebrew Hannya (Demon Plasmoid hybrid) Species Details

 Back in the days of the Blood War, where the devils openly wared with the demons, there was one minor Demon Lord by the name of Hanna.  She was madly in love with the greater Demon Lord Arlgolcheir, and she would only swear her loyalty and army to him if he promised to wed her.  He accepted, but only on the condition that they would be wed after the war.  Unfortunately for her, she and her army was vanquished, and their collective remains became another pool of demon ichor in Avernus (the first layer of Hell).  Though her purpose is long past, Hanna’s fury at never being married continued to boil in her pool of dark liquid.  

Some time later, a space-traveling ship by the name of Ionica had managed to swerve off course and be thrown into absolute planar chaos.  Aboard it was a crew of plasmoids, and they all met an untimely death as the ship dimension hopped into Avernus and crashed directly into Hanna’s resting place.  The entire ship sank below, along with the remnants of its passengers.  The ship’s hull was crushed, and the demon ichor mixed with the residue of the plasmoids.  The combination of the two organic compounds had never before been combined, and what resulted was quite curious.

From beneath the dark fluid, dark bodies began to emerge.  They were twisted, sinewy, mostly humanoid, and perpetually covered in black slime.  The only part of them not stained was a white mask made of ivory and adored with two small horns.  These new beings, called the hannya, bore a slight resemblance to their dead patron.  However, she had been dead so long that no one could recognize her inherited visage.  The hannya walked from their birthplace without allies nor resources into the harsh realm of Avernus.  Though they were still plasmoids, they no longer could reshape their form.  They were cursed to forever bear the resemblance to their forgotten patroness.

Miraculously, most managed to escape Hell.  The majority keep to the Shadowplane, where their slick black bodies and white masked faces are not offensive.  Some managed to escape into the Material Plane and serve evil masters in exchange for protection.  There are a few still trapped in Hell, and some even found a way into the Abyss.  They have no shared purpose, other than survival.  Though somewhere, deep within their dark hearts, they feel the desire to seek out the demon lord their mother wished to wed.
