Homebrew Disembodied Species Details

To cast one's mind out amongst the outer planes is the dream of many an arcane spellcaster. In recent memory, none have come closer to that dubious honor than the lost city of Ulmyr's Gate. Founded by a group of ambitious wizards who chafed under the limitations imposed upon them by government bureaucracy, Ulmyr's Gate boasted free study for all mages who sought sanctuary within its walls. The Great College quickly became a lodestone for mages of every stripe from across the empire, and for a brief moment there existed a golden age of magic.

That dream came crashing down one night when the founding mages of Ulmyr's Gate attempted a massive conjuration ritual intended to part the veil a create a permanent portal to the Ethereal Plane. It didn't work. Instead their magic  cause a massive rift in the very fabric of reality, and in an instant the entire city was tipped into the void between worlds. The entire city was presumed dead, the Arcanist Inquisition railed against the hubris if those tampering in things man was not meant to know, and life in the Empire moved on.

Years later, stories surfaced of strange people being sighted in the region where Ulmyr's Gate once stood. These people seemed oddly blurred or indistinct, and some reports said they vanished right in front of witnesses' eyes. Gradually it became clear that these poor souls were the survivors of the Ethereal Rift, now trapped between worlds and trying to retain their tenuous grasp on the Material Plane.

Disembodied Traits

You posses certain traits as a result of the magical mishap that trapped you between worlds. The disembodied are a collection of races that were in Ulmur's Gate when the accident occurred. Because of this, you choose what race you appear as. This also affects some features below, such as your height. Unless specified, you do not gain any racial features from your origin race.

Arcane Origins

You gain proficiency in the Arcana skill.

Languages

You can speak, read, and write common and two languages of your choice.

Ability Score Increase

Increase two scores ( +1 / +2 )  to a max of 20.

Age

Disembodied mature at a much slower rate than their humanoid equivalent, and their life expectancy is drastically higher, with not a single disembodied having passed due to old age.

Alignment

Disembodied tend towards no particular alignments.

Size

You still possess the height of your former humanoid self, but your nearly insubstantial nature has drastically reduced your weight to a quarter of your original weight. Your size is the same as it was before the accident. 

Speed

Your base walking speed is 30 feet.

Fade Away

As an action, you can fade from the Material Realm into the Ethereal Plane. While you remain faded away, you cannot interact with the Material Plane, and effects on the Material Plane, such as creatures or spells, do not affect you. However, you can move and hear normally while seeing everything in shades of gray. This effect lasts for 1 minute, or until you use a bonus action to end it. When the effect ends, you reappear in the Material Plane, in the closest unoccupied space you disappeared from. Once you use this feature, you cannot use it again until you complete a long rest.

Planar Outcast

You may cast the Feather Fall spell once per day, targeting only yourself. When you reach 3rd level, you may cast the Blur spell once per day. When you reach 5th level, you may cast the Blink spell once per day. Intelligence is your spellcasting ability for these spells.
