Background
Samal is a smuggler by trade, and specializes in transporting goods on and off-world without the burden of import and export taxes. When his smuggling operations become suspicious to local authorities, or he's caught in the act, Samal often dumps the cargo, flees the system, and sets up shop in a different pair of systems. This business model ensured that his illicit operations remained reliably net-profitable, but has also earned him a series of enemies in many systems, along with a poor reputation.
Outside of work, Samal fancies himself as a skilled gambler, and will go all-in far too often-- which is how he lost his ship and became stranded on Tatooine.
Motivation
Greed - Samal is powered by a desire to continuously gain more credits. He'll never have enough.
