Astral Magic

Astral Magic (also known as Astromancy) is considered to be one of the oldest forms of magic in Taeva (rivaling the equally ancient Draconic Magic), as well as the most mysterious. Drawing its power from the stars and cosmic forces of Creation, those rare few who practice Astral Magic gain the power to channel starlight, alter space and gravity, and even alter the flow of Aether itself. As a result of its exceptional rarity, as well as the immense level of skill needed to cast many of the spells associated with it, Astral Magic is largely considered to be the stuff of legends, and it's widely believed that there are still many more secrets yet to be discovered.

Effect

Starlight Manipulation
One of the most common spells associated with Astromancy, allowing the caster to channel and shape starlight. This often takes the form of firing bolts of light (which originate from above the caster), summoning orbiting motes of light, and creating constructs from light. Among the various abilities associatted with Astral Magic, this is the one people are most familiar with.

Spatial/Gravity Manipulation
Besides calling upon the power of the stars, Astromancy also allows its users to alter the forces of space and gravity. This often takes the form of teleportation, deflecting incoming attacks, and altering the effects of gravity on themselves or others, either to achieve something similar to flight or to imobilize targets.

Void Manipulation
Considered to be some of the strangest abilities associated with Astromancy, often taking the form of creating gravitational singularities and channeling void energy capable of erasing matter on contact. Due to the destructive nature of these abilities, knowledge on them is extremely restricted and well-guarded, so as to prevent them from falling into the wrong hands.

Aether Manipulation
It's widely believed that Astromancy is closely tied to the origins of magic within the Mortal Realm. Perhaps because of this connection, those who use Astromancy are said to be able to alter the flow of Aether, strengthening and/or weakening spells, and creating areas of anti-magic.

Divination
One of the most esoteric abilities available to Astromancers, granting them the ability to see through time. This typically manifests as seeing "echoes" of past events in a local area, or seeing glimpses of a possible future based on current circumstances.

Side/Secondary Effects

Enhanced Aetheric Resistance
Alongside access to a number of powerful spells, Astromancers also gain a resistance to the various effects of Aether. While this is most commonly seen as a greater natural resistance to the effects of magical attacks, it also manifests as a natural resilience against other Aether-related phenomena, including Aetheric anomalies and magical diseases.

Aether Sense
Since Astromancy is so closely tied to the forces that influence magic, it's not uncommon for those who've studied it long enough to develop the ability to naturally sense Aether in their vicinity. While useful for determining the level of Aether in an area, or what sort of magic had been recently used, it is possible for for those with this ability to become overwhelmed if exposed to a high enough concentration of Aether all at once.

Manifestation

Those who use Astral Magic describe feeling an electrifying, warm sensation when casting spells, though those who use void-related spells instead feel a cold sensation. Additionally, many Astromancy spells tend to originate from somewhere above the caster, as if being called down from the cosmos.

Source

Astral Magic draws its power from the Aether of the Astral Realm, the ever-shifting sea of Aether that surrounds all of the realms of Creation, as well as various astral bodies (such as moons and stars).
