As a part of this series, Arlo is a part of the  British military personnel that was stationed at a listening post in the Phoenix Isles. That was until a new shipment came in with a concentrated strain of the virus that infected the nuclear fallout victims. After spending weeks frequenting the radios in every country, Arlo finally came in contact with Arkina and her group; becoming the guide that they needed for safety, only being known by his codename Motherland - and addresses the team only by their codenames as well to keep it impersonal.
For Arlo's voice, I'd rather him have a British accent, as it'd go along with his character - but any other accent will do. I'd just like to stray away from the standard American accent is all!
