Currently there are seven achievable ranks. The system is simple and gameplay is much more inline with survival Minecraft in the beginning. You start without the ability to warp and are only given one home location.

Default Free Warp Commands:

• /home: Will default to your last bed-synch location
• /spawn: Will warp you to the main spawn square
• /creative: Will warp you to the creative spawn
• /anarchy: Will warp you to the Anarchy world spawn
• /terralith: Will warp you to the alternate Terralith generated overworld spawn

These are the only free warp commands in the game. As players progress, more home locations can be earned. Only Citizens and above have access to public warps (at a cost). Nobles are the only rank that can create their own warps.
