Background
Created as one amongst many, IG-7 was deployed to the Battle of Geonosis and the Defense of Dantooine like many of his fellows. Forced to self-destruct, IG-7 found that his consciousness survived, whilst his body, what remained of it, began to be passed along from merchant to merchant, each attempting in vain to rebuild him.
IG-7 eventually was found by an enterprising engineer called Illona on Jakku, who managed to cobble together enough parts to rebuild him. Reawakening after months of dreamlike awareness, IG-7 found that despite his part of programming urging him to kill her and go back to his corporate master, he could ignore it and reforge himself anew.
Becoming her stalwart companion, he finds himself forced into a life of crime - tapping back into old habits, after she fell ill. Now, he wants nothing more but to find the money to cure her - no matter what it takes.
Motivation
Find enough money to cure her. Maybe, even better, find enough money to not have to be a criminal ever again.
Obligations
Responsibility: For having repaired him and given him a sense of belonging, IG-7 feels a strong attachment to Illona.
Description
Made of a lot of hodge-bodge materials, IG-7's only identifable element of the original droid can be found with his distinctive head (which contained his core, coincidentally). He wears a cloak by default - he is used to the sands and cold of Jakku, and it just so happens that he is also a criminal who may or may not, need to hide stuff beneath a billowing cloak.
