Those born of The Abyss appear frail and weak for most of their lives, and along with the struggle of their own nature and the prejudice of the world are a strong race who are rarely ever at the disadvantage in contests of strength. making excellent use of their appearance to catch others off guard, Abyss born can often be found in less then ideal conditions as many of the abyss born do not reach the level of consciousness needed to be defined as sentient.  those that do however are often chased and experimented on as they hold a primal connection to the abyss and serve as a window into the abyss.

After the Abyss appeared, Those born of the abyss find themselves lacking a desire to choose good or evil, and as such have been in a long struggle with those on ether end. 
being born of an entity of pure destruction the abyss born understand that the circumstances of ones birth does not mark them forever and hate absolute choices.

as such they have a deep distrust for Celestial and Demonic beings. and roll with advantage in negations and CHA checks against them.

Those in the abyss are designed to destroy life, and as such each have their own weapon thats molded of their own flesh and blood.

(( this weapon may appear any place upon the body as flavor text, but must be discussed before hand for clarity)).

Years of extreme environments and grueling punishment, those  born of the Abyss all have a unique constitution based on their method of survival.  their ability to adapt and change to the struggles around them make them the perfect soldiers and even better beasts. those who have gained control of their base instincts, elevating them to a level beyond those born outside the tower. however those who do not manage to control their sanity will find themselves lulled by the call of The Abyss.
