Noumenon

The noumena are a people descended from the pure magical energies that ebb and flow on the Astral Plane.

Each individual, known as a noumenon, is a humanshaped, collection of arcane plasma that thinks and acts as an individual. Some noumena believe that they were first born when a god died in the astral plane; others believe they are a natural manifestation of that plane’s power, just as a fire elemental is the natural manifestation of the plane of fire, or a celestial is of the goodly planes. Regardless of the truth, each noumenon looks like a human , though they always glow faintly with a kaleidoscope of prismatic color.

Ancestral Traits

This unique arcane ancestry endows all noumena with certain traits.

Age. Noumena come into being as a notion on the astral plane, existing there timelessly and eternally. It is only when they fall through a colorful pool into the material plane and merge with a developing human fetus that a noumenon is born. After that point, they reach maturity more quickly than a normal human, by age 10, and can live until their magically enhanced human form gives out, in roughly 500 years.

Size. Noumena are human in shape and size. Your size is Medium.

Speed. Your base speed is 30 feet.

Inherent Magical Essence. Noumena have advantage on saving throws against spells and other magical effects. However, spells and abilities that sense magic, such as the detect magic spell, locate noumena.

Furthermore, their magical auras cannot be hidden by spells such as arcanist’s magic aura. If the dispel magic spell is cast on them, they must make a Charisma saving throw against the caster’s spell save DC or be Stunned until the end of the caster’s next turn. Finally, if they enter an anti-magic field, they must make a Charisma saving throw against the caster’s spell save DC or drop to zero Hit Points.

Magical Attacks. A noumenon’s very body is a magical thing. Your unarmed strikes count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Cultural Traits

Noumena communities are few, but those that gather usually do so around a portal to the astral plane, granting them access to their home planes, which they often visit. Otherwise the primary pastime of noumena is the study and practice of magic. Everyone raised by noumena gains the following traits.

Magical Acumen. Everyone in noumenon culture is taught a few magic spells. You know the prestidigitation cantrip. When you reach 3rd level, you can cast the detect magic spell once with this trait.

You regain the ability to cast these spells when you finish a long rest. Intelligence is your spellcasting ability for these spells.
