Character concept: A Tremere Assessor, trying to infiltrate the Order of Suleiman.
Why has he come to Capernum: It's a useful base for his work. In practice, he'll probably spend considerable periods of time away from it when "undercover".
I'm not going to post a full character sheet yet (due to a combination of time constraints and wanting to get the basics settled to minimise rework). His proposed virtues and flaws are as follows:
Virtues: The Gift (Sp), Hermetic Magus (FSS), Minor Magical Focus: Certamen (FH), Gentle Gift (MH), Second Sight (mSu), Persona (mSu), Quiet Magic x 2 (mH), Subtle Magic (mH), Cautious Sorceror (mH), Life Boost (mH).
Flaws: Dark Secret: Spy for the Order of Hermes (MSt), Higher Purpose: Prevent the fall of the middle east* to infernal corruption (mP), Weak Magic Resistance (when shapechanged) (MH), Vulnerable Magic: ? (MH).
*Or more period appropriate name.
I think the potentially controversial things there are the Dark Secret, Weak Magic Resistance and Vulnerable Magic. The Dark Secret isn't really going to be a secret to his allies, but will mean that every now and again a situation appears which risks blowing his cover. Weak Magic Resistance applies when he's using a Persona (as well as any other type of shapechanging magic), which gives him a reason to change back into his true form (and possibly cackle and monologue) when his cover is sufficiently blown. Vulnerable Magic I haven't quite decided upon, but I'm thinking of something linked to his true identity - maybe someone calling him by his true name three times, or something. That might be a bit hard, though? It does return him to his natural form in addition to its other standard effects.
Tariq was born to a bedouin tribe in Arabia. As a young boy, he could see the evil spirit whispering in the ears of the tribe's Sahir, driving him to ever greater cruelties against them. Things came to a head when the infernal jinn demanded that he start sacrificing victims to it - including the boy. He was rescued in the nick of time by one of the Redcaps the then Primus of Tremere had encouraged to find Gifted African and Arabian children. The Redcap took the boy back to Translyvania, teaching him his own ability to change form in the process, and "Tariq" spent the next 15 years as Janos, a Hungarian herdsman's son, training as a spy to go back and infiltrate his native lands.
Note: technically he's scrying whenever he's in his Hungarian form (which is going to be most of the time around Franks). He's not keeping that it isn't his native form a complete secret (although anyone below the level of a magus is unlikely to be aware of it), but given it's the form everyone knows as "him" it seems at the level where he's unlikely to get seriously prosecuted. Shout if you disagree.
