Your innate magic comes from the entropy that eats away at the foundations of creation. You most likely cannot trace your magic to any source, as it your magic comes from nothingness itself.

Entropic Gaze

Starting from 1st level, you have truesight with a range of 30 feet. 

When you reach 11th level in this class, you learn the True Seeing spell, which doesn't count against your number of sorcerer spells known, and which you can cast without material components. In addition, you can cast it by spending 3 sorcery points or by expending a spell slot. 

Antimagic Aura

Starting from 1st level, ranged spell attacks made against you are made with disadvantage. 

At 10th level, you gain advantage on saving throws against spells.

When you reach 15th level in this class, you learn the Antimagic Field spell, which doesn't count against your number of sorcerer spells known, and which you can cast without material components. In addition, you can cast it by spending 5 sorcery points or by expending a spell slot.

When you reach 20th level in this class, the spell Antimagic Field has a duration of 1 day and no longer requires concentration.  

Void Attuned

You become familiar with the harsh conditions of the vacuum of interstellar space, allowing you to draw more power from the void. Starting 6th level, you don't need to breathe, and you gain resistance to cold damage.

Additionally, if you have no spell slots or sorcery points remaining, you can still cast a spell, but in exchange gain one level of exhaustion. 

At 17th level, you gain immunity to cold damage. Additionally, you no longer require a long rest plus food and drink to reduce your exhaustion level, all you need is a short rest. 

Empty Vessel

At 6th level, you gain resistance to psychic damage. Additionally, you are unable to be targeted by the spells Detect Thoughts or Modify Memory.

At 15th level, you gain immunity to psychic damage. 

Mage Counter

At 14th level, you learn the spells Counterspell and Dispel Magic if you don't know them already, and they don't count against your sorcerer spells known. If you know one or both of them already, pick one or two 3rd level spells to learn from the sorcerer spell list to learn instead of Counterspell and/or Dispel Magic. Those spells also don't count against your sorcerer spells known. 

Additionally, you learn the spell Remove Curse, and it doesn't count against your sorcerer spells known. 

Dust to Dust

Starting at 14th level, when you reduce a creature to 0 hit points, it disintegrates. A disintegrated creature, excluding what it is wearing and carrying, is reduced to a pile of fine gray dust. The creature can be restored to life only by means of a true resurrection or a wish spell.

Avatar of Oblivion

At 18th level you can choose to fully embrace the destructive forces of entropy. As an action, you can choose to spend all of your remaining sorcery points. As a result, all creatures (excluding yourself), objects, terrain, spells and magical effects within a 30 feet sphere centered on yourself is disintegrated into fine gray dust. Additionally, you gain 1 level of exhaustion. If you use this ability without having any sorcery points, you gain 2 levels of exhaustion instead. 

A disintegrated creature and everything it is wearing and carrying, including magic items, are reduced to a pile of fine gray dust. The creature can be restored to life only by means of a true resurrection or a wish spell.
