Our understanding from your app is that Hanzo's "exile" from Tevinter was entirely self-imposed due to conflicts internal to his family, and as you said he's been gone for 10 years, so unless he's going to go around introducing himself to the authorities by name and reminding them of the crimes he committed a decade ago, it doesn't seem like there ought to be anyone after him. But if there's an element we're missing here, or if you think that his family would cause problems in some way, please let us know so that we can consider what the consequences might be.
