The Monstrous Half Drow

Unlike their Wood and High-Elf cousins, the Drow are far more likely to consort with demons and dark gods like Lolth or Vulkoor. These interactions can lead to the creation of monstrous half-Drow amalgamations, the Scorrow, the Driders and the Draegloth.

Large Creatures

The Drider, Scorrow and Draegloth are all Large races. They follow the Jotungard rules for Large Races by /u/SwordMeow. These are as follows:

The races have advantage on Strength ability checks and Strength saving throws. For this reason, these races are assumed to be strong, and do not need to gain a Strength score bonus—they will usually roll high anyway, except on attacks and damage.
If you are proficient in any weapon, you are considered proficient for its Large sized version as well. The Large versions of weapons are not very common. They cost at least twice that of a normal weapon. You may start with a single Large-sized weapon.
The Large weapons deal an extra 1d4 damage.
Your normal unarmed strike damage is 2 + your Strength modifier.
The creature takes up a 10 by 10 foot area.
To fit into a Medium area, the creature must squeeze into the space costing double its movement, disadvantage on attack rolls and Dexterity saving throws, and attack rolls against it to have advantage.
The creature's push, drag, lift, and carrying capacity are all calculated for Large size. Push, drag, and lift are 60 times your Strength score while carrying capacity multiplies your Strength score by 30 unless otherwise noted. The races are able to grapple and shove Huge creatures. If you attempt to handle something very small, such as a vial of acid, the DM may call for a Dexterity check where a smaller sized creature would automatically succeed.
You require mounts at least one size larger than you as normal.
You require four times as much food as normal and your armor requires four times the materials to be made. It is about that much more expensive, and that's assuming you can find it. Based on how common these races are in your world, they might be found in populous cities. You also require larger shields, which are more common, but give no bonus to AC outside the norm.
All of these races still count as humanoids unless otherwise noted.

Balancing Races

The Drider and Scorrow races are both balanced using the "Detect Balance" system for 5e. Large is considered a 12 and their "Half-Drow" Trait is considered a -6 as it removes the Large Weapon bonuses that Large races usually have.

Scorrow

"A jet black warrior, the upper half of a lithe, lethal drow and the lower half as a massive scorpion with a stinger that reaches over his shoulder. The sickening green venom that drips from its barbed hook is also laced over both of the wicked underhand knives."

Created, Then Born

Scorrow are the horrifying half-drow half-scorpion amalgamation created by the Drow God, Vulkoor, who has an affinity for Scorpions. The first Scorrow were blessed by Vulkoor and given these monstrous forms. Unlike Driders, Scorrow are a true-breeding race and nearly all Scorrow are now born of Scorrow parents.

Desert Hunters

While Driders and Drow native to the Underdark scorn the sunlight, Scorrow and their Xen'Drikari Drow counterparts carve out their existence in the deserts of Xen'Drik. Scorrow are voracious hunters and will choose to hunt prey based on difficulty involved in the hunt. The prefer very challenging creatures and will follow a very long trail just because they love a difficult hunt. Scorrow have an intense hatred of Giants that they share with their Xen'Drikari Drow cousins.

Revered Outcasts

Scorrow are revered by Xen'Drikari Drow as those blessed by Vulkoor, but are outcasts from Drow society. Scorrow are incredibly disdainful of weakness, even so far as to abandon their young if they are too weak. They act as solitary hunters, or live in small, but powerful nests of up to five.
