Due to their extremely light and slender bodies Astrals are very fast, agile and flexible.

Astrals aren't born but created and start of as young children around the age of 4. Aging twice as fast as humans it doesn't take long until they reach adulthood at around 20-22 years in human years. After that they stop aging alltogether and therefore are somehow immortal as they don't die of old age.

Seeing as their is almost never any conflict and a lot of empathy towards each other in the Astral world most Astrals which were raised there tend to be within the good spectrum. If however an Astral was banished for a evil deed towards his brothers and sisters or if they journeyed into the world at a early age and were raised in a fitting environment, for example Ignominia, they can also appear as neutral or evil.

Due to in nature tall and lean stature they look similiar to elves. Ranging from 5'7 (1.7m) to 6'3 (1.9m) they are larger then most humans.

Their extremely light build and the ability to levitate gives Astrals a impressive speed of 50 feet  (15m). Thanks to this they are also able to climb fast and efficient, being able to scale mountains at a speed of 30 feet (9m).

Thanks to their natural sensitivity and knowledge in magic Astrals are able to change into their native way of seeing, seeing as how most of the Astral world is made of magic. With this an Astral can see magic and the manipulation of this in a 65 feet (20m) radius. This  however prevents them from seeing anything but magic, giving them disadvantages on any skill check requiring sight or precision.

An Astrals manifestation consists mainly of Astral magic, which is fundamentally different then the magic of Nemiris that relies on the weave or shadow weave. While an Astral might not be able to use conventional spells they however aren't affect in other ways by dead-magic zones or antimagic fiends and effects. High level Astrals might even be able to use Astral magic while under the influence of these restrictions.

When a Astral dies on Nemiris their soul gets pulled back into the astral world. If they die within their homeworld their souls do not get destroyed but shattered. These fragments, including many of other dying astrals, then form a new astral. This also is the reason why Astrals never feel lonely and may have knowledge that they have not personally experienced yet. When sleeping or meditating an Astral can try to connect to their past selves to gather information, opinions or even to just talk. The effectiveness of this depends on the Astrals wisdom.

In the situation that the hosts life may be seriously in danger an Astrals may take control of their hosts body, in the process fusing their life force and making their Astral magic flow through the host, which enables them to use the same spells as the Astral. This ability however can be a serious strain on the host, especially weaker ones. Using it for to long or too much without letting the host take a long rest may result in unfit bodies being burned from the inside out. This hoewever does not seem affect very powerful hosts like dragons or lichs much.

The magical aura emitted by Astrals and their extreme lightness allow them to levitate roughly 8 inches (20cm) above the ground at any time. With enough strength and concentration they might even levitate higher for short amounts of time. Astrals can however be grounded forcefully by insulating their aura, which causes them to be slowed down to a walking speed of 30 feet (9m) and climbing speed to 17 feet (5m).
