I had a great idea for a young Church-schooled Irish come Celtic rocker.  I would have to edit this as the original character was a half-elf for d20 Modern.  Please comment and see if this would work.  I wouldn't mind making him a Witch/Warlock/Wizard/Whatever guys who can use magic are called.   Faery-type magic would be perfect here... charms, illusions, glamers only, maybe some ability to use "Magic Items", whatever they'd be.
[sblock=Rory Shanahan]Rory Shanahan was born to  Deirdre and Finn Shanahan in South Boston,  Massachusetts. Rory’s  official birth name is Ruaidhri O Seanachain; his  mother wanted to keep  ties with her Gaelic roots.
 
Rory grew up well-to-do in a decent Irish neighborhood.  Deirdre was an   attentive and lovingly strict stay-at-home mom, and Finn worked at a   public relations firm.  His mother had high hopes that Rory might become   a Catholic priest.  As soon as he was of age, his mother enrolled him   in the South Boston Catholic Academy, then to Boston College High  School  and Boston College itself.  
 
At first, Rory wanted to please his mother and embraced the Catholic   lifestyle.  He became a member of the school choir and dedicated his   time and energy to his studies.  As he progressed into his teens, he   began to question the universe and his place in it.  By the time he   reached university, he grew tired of the Catholic “programming” and   wanted to experience life outside of school walls.  He began to spend   more time in the local pubs than in school.  During his nightly forays,   he encountered a local Celtic Rock band who called themselves “Primal”.    Celtic bands were a dime a dozen around Boston, but this band had a   rainbow-haired bassist named Twilight who looked like a Gypsy on-stage.    Rory was immediately smitten, and like a school boy with a crush,   followed the band around the city.  Each night, he would try to strike   up a drunken conversation with Twilight, but the lead singer Donovan   would always intervene and turn him away.
 
One night, Rory noticed some tension between Donovan and Twilight,   tension that carried over into the band’s performance.  Midway through   their set, Donovan surprised everyone by angrily throwing his microphone   on the stage floor and storming out of the pub, uttering a string of   expletives as he left.  The band looked confused.  With a rush of   adrenaline, Rory hopped up from his bar stool, jumped on stage, and   picked up the mic.  Before anyone could stop him, he began to sing one   of the band’s songs a capella.  The band looked at each other, shrugged,   and one by one began to accompany Rory’s singing.  By the end of the   show, the bar was cheering and chanting for an encore.  Later that   evening, the band thanked Rory and asked if he wanted to come on   full-time.  
Twilight warmed up to Rory, and in short order they became an item.    Twilight soon revealed to Rory that she was a Wiccan, which provided   Rory some insight into a new (yet very old) religion that refreshed his   mind and rekindled his interest in learning.
 
Donovan appeared one afternoon during a rehearsal with a chip on his   shoulder.  He “thanked” Rory for holding his place and shoved a fistful   of bills in his chest.  He then took his usual place on stage and   commanded the band to start playing.  Twilight confronted Donovan and   told him that he was no longer welcome in the band.  Donovan threw a   fit, then cautioned Rory to “watch out for dark alleys” before leaving   in a huff.
 
As the band toured the city’s drinking establishments, Rory began to   start noticing odd things happening around him.  He would often see a   flicker of movement, or a twinkle of light, or hear soft, unintelligible   voices out of nowhere.  He asked Twilight about it, hoping that he   wasn’t going crazy.  Twilight suggested that it was possible that   faeries may be trying to communicate with him.  Although he himself did   not believe in faeries, Rory knew that Twilight took her craft   seriously.  Together, they delved into the college library and the   Internet for whatever they could find regarding faeries.
 
During her research, Twilight discovered that the Shanahan family had a   legacy of wealth passed down from generation to generation, presumably   from Irish royalty.  The wealth was recorded as being a gift of the Fey   folk, but there were no factual references to the source, or in what   form the wealth existed.  Rory knew nothing of this legacy.  He   approached his parents with the story and received the shock of his   life.  His father's form appeared to ripple and waver.  Rory blinked his   eyes, and when next he looked upon his father, he did not see the man   that raised him, but a tall, slender creature with pointed ears!
 
The creature talked with Finn’s voice, but it was clearly not human.    Finn explained that he was, in fact, an Elf.  He did not originally come   from this world.  There existed, somewhere, a whole other realm full  of  fantastic creatures and races and magic.  Finn used to live there,  or  at least, he believed he did.  He explained that Elves had an  unusually  long lifespan and the event recorded in the library’s  journals happened  some four hundred years ago.  He originally appeared  in Ireland with a  large chest of gold coins that he “liberated” from a  faerie wood.  His  voice became grim as he noted that the gold was  cursed somehow; he had  no way of returning the chest to the original  wood, and the Fey had long  memories.  Rory shared his odd experiences  with Finn, who confirmed  that Rory’s Elven blood made him sensitive to  Fey Folk, among other  possible gifts.  Finn did not know for certain  how said gifts would  manifest in a largely non-magical world, but  hinted at feats of magic.   Deirdre added that she hoped, by becoming a  priest, Rory might find a  way to break the curse once he became wise  and educated enough to  understand it.
 
Rory renewed his studies with a fervor unseen since his younger years.    With the guidance of his father, Rory found that he could in fact   manifest a few simple tricks in short quantity.  Rory shared all of this   new information with Twilight.
 
Twilight confirmed that she already knew of his Half-Elven heritage   because she could see the same world to which he had previously been   blind.  She added that she knew of a group of people who dedicated their   lives to ensure that which is hidden remains hidden.  Perhaps there,   she advised, he could further his magical arts, or learn more about the   cursed gold.  She gave him directions to a contact with the group.   With  sad farewells (and apologies to his mother), Rory jumped on the  first  bus out of town and made his way towards his destiny.[/sblock]I keep forgetting that if this is the Buffy/Angelverse, any story with any supernatural element is fair game.
