Help Developing the Other Main Character...

I have pretty much finished my Wych character Zehra's background story for the most part but I need help with teh other main character in her story, a high rankking Archon of the Kabal of the Black Heart, called Xyritaan Delfaughn.
He is the Trueborn son of the Archon of the Kabal of Poisoned Lashes, Revidar Delfaughn and his favored concubine Diha Ruraraad. A
ll I have is that one day he cut all ties from his family Kabal and started wearing a mask, after swearing allegiance to the Kabal of the Black Heart.
I have mainly thought of his mask just being a regular mask of metal. Also he has no scarring on his face, he is actually quite handsome, so he's not wearing it for that reason. Cavash suggested to me that if he made a Hell Mask out of his former master's face it could be a way to symbolize his loyalty to Vect.
I also need some help with a minor backstory for Haemonculus Telkarris Veldarrn who raises Zehra, to help make his reasoning on sparing her and not really marring her so she looks physically perfect. I am debating having him do experiments on her muscles and stuff as a child...
One other thing, please let me know if any of these Kabal names I've used are taken by anyone else. I used a Kabal/Wych Cult name generator I found but it had limited response and I really don't want to steal anybody else's names for their Kabals.
Zehra's Father's Kabal - The Kabal of Eternal Torment
Wych Cult Zehra is trained in - The Cult of Despair
Xyritaan's Family Cult - The Kabal of Poisoned Lashes.
Any help is appreciated, so please give me your feedback!

Yay, charecter development! I always love helping things like this.
I shall brainstorm for a bit and get back to you later.

Moved to Stories section because of the fluffy nature - Cavash.

Thanks, Cavash, I'd really like both yours and Malys input.

To others he could appear to be extremely arrogant and vain, wishing to deny others of the privilege of gazing upon his true face but on the inside he could feel great shame. He could have betrayed his family and his Kabal to serve under Vect, but after slaying his former master/father realised the shame he had brought upon his family’s name. That could be a reason to wear a mask made from metal.

Also, when he was just a Trueborn child, he could have had dealings with Hellion and street gangs that nobody was supposed to know about. These gangs could have been insulted by the Trueborn not wishing to pay them in whatever cargo they demanded for a certain job so, instead of becoming violent, they slinked off into the dark to gather their resources over the cycles.
After many cycles they could have found the wealth to hire numerous assassins, each given the task of slaying the Nobles of Poisoned Lashes.
He could have made some fancy escape when he realised what had happened and sought protection under the Black Heart Kabal.
The mask could have been to hide his identity in the cycles spent seeking out the Black Heart's territory, as when he travelled through the deepest labyrinths of Commorragh the Hellion/street gang were hunting him.


I hope these ideas pose as good inspiration.

Thanks Cavash, they certainly give me something to think about.
