Sith Warrior
From Starbound Awakens
Armed with Force Lightning and a Lightsaber, Sith Warriors are offensive NPCs/Tenants. They may occasionally be encountered as enemies, but Sith Warriors as tenants can be fairly profitable, with their ability to gift you with Life Essence, Lightsaber components, as well as highly coveted Datacrons, which will usually contain the secrets of how to "learn" Force Lightning and Force Grip. On occasion, they will also give you Sith uniforms or Ancient furniture pieces to decorate your base.
