Homebrew Calvergeist (Skull Specter) Species Details

There are stories told of apparitions or spirits that slip their way into the material plane to haunt the world of the living. The energy of the soul that is remained from them or leaked from the ethereal plane will root itself into the Skull of a long-dead beast. This energy will build over the course of years until it builds enough of it to birth something new. A Calvergeist is formed from the ectoplasmic energy giving it a state of psudo-corporealness comparable to that of any mortal being. 

The life or a Calvergeist is strange, as they do not start as anything like a newborn child but more of a wandering nomad spending years in a foggy state just barely sentient. After time spent learning and forming this new person, they begin to generally try to find a place in this new world. Due to their fragmented memories and resilient physical form they often find themselves as guardians of ancient temples, archeologists, or even rare adventurers.  

Physically speaking the physical form of a Calvergeist is a wide range. They all share the common trait of the Skull that holds their essence. This skull can be anywhere on their body such as 'Worn' as a helmet, rested on their shoulder like a piece of armor, or centered in their chest. The skull is extremely durable and is said to only ever break if the person would to die. The form of the person itself is also strange it can look very humanoid but always tend to have strange skin complexion and hair (such as bone-white hair and translucent skin or colorful sparkled skin and changing waves of color in the hair). They can also take a form more suitable to the skull they inhabit being more bestial  in appearance.
