'Unique Skill: Onyx Lord's Repulsion Thrust the armament into the ground to create a gravity well. In addition to dealing damage, this attack sends enemies flying away.' The Onyx Lords are the Alabasters' dark-stone counterparts, same meteor-born stone-skinned race, opposite gravitational polarity. Where the Alabaster Lord's signature skill is a pull-spell that draws enemies inward, the Onyx Lord's Repulsion is a push-spell that hurls them outward. Both are thrust-into-the-ground gestures that tap the same meteoric ore in the bedrock ; the polarity is what each lineage chose to emphasise.

'Unique Skill: Alabaster Lord's Pull Thrust the armament into the ground to create a gravity well. In addition to dealing damage, this attack pulls enemies in. Has a greater area of effect than Gravitas.' The pair's binary reads as a rare canon-level metaphor for the universal force itself. Gravity is bidirectional in physics, the same field that pulls planets together pushes their atmospheres outward at scale. The Alabaster–Onyx Lords codify the pair as a doctrinal split : two academies of stone-skinned ancients who chose, after their meteor-birth, to specialise in pull and push respectively. Both reside in the deep tunnels of Sellia and Nokron, where their bodies are slow but their pedagogy is patient. Radahn studied both. The conqueror of the stars learned to manage gravity from teachers who did not, themselves, ever leave their stone classrooms.
