Aether Vortigern

Aether Vortigern is the head of the assassin Momerath Family, the second most powerful family within the Vortigern Clan. The older brother of the former clan patriarch Gildas, the century-old assassin has a very extended family, making the Momerath the largest in terms of numbers.

Abilities
Despite his advanced age, Aether's physical body remains at good physical condition, boasting great attributes all-around.

A master of all Vortigern techniques, he is the pinnacle martial technician, with extreme deadliness against individual targets. With Arasian, he can detect other Aura-users from 30 meters away and predict their moves perfectly. With Gangas, he can move at great speeds with fine control. His Brecan is so powerful that an otherwise normal punch can cause people to explode from the inside, while Forfeallen allows him to negate most projectile-based, object-based or physical Semblances.

Aura
Aether's Aura manifests as his namesake, aether. His body is surrounded by mesmerizing strings of gentle light and his Aura shield, instead of being a single smooth barrier, is a multitude of said strings curling around him much like a fraying cocoon, making his defensive area both extensive and erratic, with the concentrated strings resulting in incredible strength. His aether is akin to the pure essence of the universe, with perfect convertibility into all other elements and energy.

Aether's Semblance is "Aether Control: Perfect Purity". His ability grants manipulation of his unique aether Aura, utilizing it in a huge variety of ways, while converting it into different elements and energy when desired. This essentially allows him to generate and control all elements and energy, so long as it originated from his aether Aura.

Over his century-long life, Aether has gained mastery over his Aura and Semblance, being able to convert his aether in a split-second, shape multiple streams of elements at once, concentrate the direction vector of his energy to create powerful energy blasts, form mind-bullets in an extended area around him, fine-tune the energy's properties, such as voltage, to the point he can power delicate electronics and achieve telekinesis. He can even convert his Aura into other Auras to recharge and empower other Aura-users.

Aether's primary weakness is that he was never blessed with great Aura capacity. While energy-wise he is perfectly on par with many with high Aura capacity, it takes a lot more out of his soul to form aether Aura, hence denting how much Aura he effectively has. As a result, his otherwise unbeatable Semblance cannot last, only managing four minutes at the highest usage. If he mainly focused on matter elements, their persistence mean he can sustain on an initial investment of Aura, while using energy forms, though more malleable and powerful, would result in continuous Aura usage due to said energy's natural dissipation. Hence, Aether is very powerful when fighting individuals, but falters slightly with groups and does not have the energy to generate huge attacks against armies.
