Sellsword is exactly that: a mercenary who does not care what he's been hired for. Executions, body guarding, just bring a paycheck and Jake Picaroon will handle the details. After all, he had a gold washed set of armor he'd like to get out of hock. He was Childe's third minion, and is basically only hanging around for the money. He has a shared enmity with another member of the group, one Commander Raven.
