The Ranks/Realms, in ascending order: Student, Practitioner, Master, Grandmaster, Venerable, Perfector, Transcendent.
Students are everybody who has learnt something about Qi but is not a Practitioner. A Practitioner is somebody who has sensed Qi. A Master can control Qi inside his body ( aka Inner Qi ) and a Grandmaster can control Qi outside his body ( aka Outer Qi ).
When a Grandmaster has found his Path ( basically find their meaning in life ) and begins walking on it, they become a Venerable. Once a Venerable has perfected their Path, they become a Perfector. A Perfector needs to transcend their Path to become a Transcendent. It's harder than it seems.

These are the Ranks for Artifacts, also in ascending order: Pseudo-Artifact, Spirit Artifact, Master Artifact, Grandmaster Artifact, Legendary Artifact, Perfected Artifact (sometimes Prime Artifact ) and Transcendent Artifact. Each of them corresponds to one of the Power Ranks/Realms.
