[Progenitor Ability] Meaningful Ressurection
The more the Progenitor dies a meaningful death, one that alters destinies, ends eras, or births new meanings for others and himself, the stronger they become upon returning.
[Energy Affinity] Chaos
First Circle
[Authority of The Meaningless (1st Stage)] Experiencing first-hand the abilities of other Sin users grants knowledge about their Sin's properties and limitations.
[Null Presence] Others overlook your existence, forgetting details about you easily. Tracking abilities, clairvoyance, and even fate-based targeting struggle to lock onto you. This ability also allows you to become invisible against people who do not actively seek you out.
[Null Presence (First Death)] When Null Presence is activated, the physical limits of your body will become meaningless. Allowing you to naturally exert brute strength, flexible movements, along with inhuman speed and senses. (This ability is limited to the Progenitor.)
Second Circle
[Authority of the Meaningless (2nd Stage)] Your authority allows you to take away an item's "purpose" and relocate it. Your destiny has also become masked from certain divinations, making fate slightly meaningless against you.
[Fate Consumption] Consume a selected portion of a target's fate to empower yourself, momentarily giving your identity a "purpose."
[Word of Silence] You hold power over the word "silence". Once uttered, all those that hear it will halt their actions and your environment will temporarily become solemn.
