Taric's name most likely originates from the Arabian name "طارق/Tariq", which means "The striker." A commonly used Quranic idiom of tariq also relates it to brilliant stars, furthering its connection to him as a character.
Taric is likely left handed, as that is the hand that wields his hammer (though some of his splash art portrays him holding it in his right).
The in-game description for GemcraftTaric is a reference to Diablo 2's gem socketing.
