Homebrew Phasewalkers Species Details

The Ethereal plane borders all of the material realms, and its influence is seen in the presence of phase spiders and blink dogs. Phasewalkers are the planetouched humanoids of the Ethereal plane Belonging to neither the Ethereal plane nor the Material plane, they have the ability to move between the two.

Close but Far Away
As rare beings, Phasewalkers might go their entire lives without encountering another one of their kind. Though they can easily cross the border to the Ethereal plane, they often can not stay there for long. Phasewalkers almost never come into contact with the source of their heritage. 

Born of Æther 
Phasewalkers appear as pale-skinned humanoids with blue, translucent, pupilless eyes. If you look closely at them, the edges of their form seem to be wavy, or blurred, as if not truly formed. Their ability to shift to the Ethereal plane makes them naturals at stealth.
