You spent a period of time enslaved by a crimelord.
Tortured: The crimelord tortured you and left you for dead on a garbage heap after you made one too many errors. Your scars and memories have honed your reaction speed and make you rather jumpy. You gain a +1 bonus on Reflex saves.
Religious: You found a holy symbol of the god you worship today while on a job for the crimelord and, intrigued by it, you snuck off to attend services. When he found out, he beat you to within an inch of your life and broke your holy symbol. Your faith let you block out the pain, and you escaped his control and took shelter in the church, where you spent the rest of your youth. You gain a +2 bonus on Concentration checks.
