Zar'ithra

Zar’ithra (plural zari’thra’rin) or the shadow draconic drow was an offshoot of the drow race and were primarily found in the city of Chaulssin. They were the non-first-generation drow offspring of the shadow dragons of Clan Jaezred and thus were not half-dragons, despite this they exhibited some draconic characteristics and possessed stronger ties to the Plane of Shadow than their zekyl compatriots.

Collectively, they had a predisposition towards sorcerous magic.

A genetic quirk of theirs was that the offspring between them and a drow-dragon was almost always a male zekyl.

History
As mentioned above zar’ithra is the name of the non-first-generation offspring of Clan Jaezred’s shadow dragons and the drow of Chaulssin, who were enslaved by the dragons. In 634 DR, the dragons were overthrown and in 734 DR, the now free citizens of Chaulssin escaped to the Plane of Shadow to evade the armies of Menzoberranzan bent on killing them for being heretics. On the Plane of Shadow, they were part of the founders of Chaul’mur’ssin. After their zekyl compatriots learned a way to divide their dragon and drow lineage, the creation of the race of the drow-dragon, they returned in meaningful number to Toril in 1136 DR. In 1372, the majority of the zar’ithra lived in Chaulssin and while they outnumbered the zekyl population in Chaulssin, they formed only a small minority in the Jaezred Chaullsin’s membership.

The ones in Chaulssin had the duty to defend the city both from intraplanar as well as from extraplanar foes from the Plane of Shadow.

About 80% of the harems of the Jaezred Chaulssin’s leaders consisted of them.
