Background for Eurid Turnstone:
Stephon Turnstone of Shadowdale, a paladin of Helm, first stumbled his way into the Cage nearly forty years ago. With no immediate route back, he fell in with the Harmonium and eventually came to consider Sigil his home. The faction was good to him, and soon he enjoyed the privileges of rank and title, purchasing a modest home in the Lower Ward and even taking a tiefling wife whose outward manifestions of her fiendish heritage were more succubus than balor. The two had eight children, of which Eurid was the youngest--all of them, save the last, shared their mother's tendency toward elegance and passable human appearance. Eurid, with his rat-like tail, deformed hand, and other odd traits stood apart as a shock to his poor father.
Stephon was a good man. He struggled and fought and wracked his conscience, but he could not bring himself to love the little monster he'd created. As the other children prospered in their father's love, Eurid had only his mother. As the others basked in unconditional support, Eurid struggled to follow in his father's religious training. He eagerly delved into theological study. He grew strong scrapping with older brothers who learned their father's disgust, but not his remorse.
When the Ooze Boils plague came to Sigil (a magical plague effecting abyssal tieflings, which escaped from the battlefields of the Blood War), Eurid's mother and three of his siblings succumbed and died in agony. Eurid was nine years old. Stephon took his surviving children and departed for Toril, but knew there was no place for his most fiendish child there. The boy was left with the Dustmen who tended the hospice where his mother and siblings died, and he was eventually deposited in an orphanage.
Unlike with most tales of this sort, Eurid found his new caretakers to be both kind and compassionate. His time at the orphanage was not all together unpleasant. And, by his continued study and natural talents, he was inducted into a small community of Kelemvor-worshipers within the Dustmen at the age of 16. Since then, he's completed many tasks for his faction and proven himself among his peers.
Appearance and Tiefling Traits:
Eurid is handsome by tiefling standards, and among the unprejudiced and cynical Cagers there are few who think twice of his tail or odd left hand (a wad of meaty tissue with three fingers sprouting at odd angles like a grasping claw--suitable for bearing a shield or grasping a torch, but not much else). His strangest feature is metabolic. He sweats coal-dust and stinks of brimstone and sulfur when overly exerted. Due to his upbringing, he is uncharacteristically vain about this particular quality, and so wraps his arms, chest, and throat with perfumed strips of linen which he changes almost obsessively as they inevitably stain black with filth.
Current Undertaking:
Eurid's mentor among the Dustmen (a human priest of Kelemvor) passed away recently. Among his personal effects, Eurid discovered a concerning letter expressing some troubling doubts about the Dustman philosophy which his mentor apparently kept secret. The questions raised in the letter are very esoteric and philosophical in nature, and so of little interest to anyone outside the faction. Eurid has found them difficult to answer, and they've left him with concerns that his beloved mentor may have failed to pass on to the True Death. For this reason, Eurid has requested and received some personal time away from his faction duties. He hopes to go out on his own for a time, away from his comfort zone and social bubble of like-minded folks, so as to gain some new insight that might help to shore up his faith.

As for the magical items, Eurid will take a +1 longsword and that golden ring with the worn-off insignia. Unless you have a different plan for where it came from, we can say it was among his mentor's belongings.
