Drow-dragon

Drow-dragons (or Draa’zekyl) were an offshoot of both the drow and the shadow dragon, more precisely of the zekyl.

Abilities
They were shadow dragons but at the same time also drow. They had the same abilities of the shadow dragons which they developed more and more by accumulating age but added to this came the ability to change into an individual drow form and back to dragon form. They could stay in either form for an indefinite amount of time.

They had collectively a predisposition for sorcery.

History
The drow-dragon was not a race that sprung on its own. All drow-dragons trace their ancestry back to Clan Jaezred, a clan of shadow dragons who enslaved the drows of the city of Chaulssin in -221 DR but were killed by their own half-dragon offsprings and servants in 634 DR. The population of Chaulssin then travelled to the Plane of Shadow to evade the armies of Menzoberranzan bent on killing them for being heretics, in 734 DR and after founding their city Chaul’mur’ssin, they came into conflict with the Clan Malaug.

During this conflict, House Jaezred, at that fulfilling the duties of a secret police dedicated to find and kill shapeshifting infiltrators, stole the necessary magic to divide their dragon and drow parts from the malaugrym and the race of the drow-dragon was born.

In 1136 DR, House Jaezred, and with it a few drow-dragons, returned to Toril. In 1372 DR, nine drow-dragons are known to exist on Toril, whether and if yes how many of them lived still in Chaul’mur’ssin was not known.

Eight of the aforementioned drow-dragons formed the leadership of the Jaezred Chaulssin, the ninth was the Jaezred Chaulssin’s leader Mauzzkyl Jaezred’s daughter Nurvureem.

Reproduction
The reproduction of the drow-dragons, not the act but the result, was a mystery. On one hand, a child between a drow-dragon and a drow was stated to be a half-dragon. They had a tendency to produce more male half-dragons than female ones, but those were still half-dragons. Nurvureem, Mauzzkyl’s daughter as mentioned above, was kidnapped in 1241 DR while still in the womb of her mother and only found in 1358 DR. She was already a drow-dragon despite not having undergone any rituals to turn her into one.
