Roa's Rules were a series of honorable maxims and common-sense tenets developed by the smuggler Roa when teaching young smugglers the trade. Han Solo, among many others, learned these rules at his side. * Never ignore a call for help. * Never take from those who are poorer than yourself. * Never play sabacc unless you're prepared to lose. * Always be prepared to make a quick getaway. * Never pilot a ship under the influence.
