Traits

Those with this trait have a face/head with at least 50% of it being made of bone.
Those with this trait can have the eyes represented as an empty socket or as a small, colored dot. The 'dot' for the eye may not glow unless used in conjunction with the Glowing Eyes trait.
This trait automatically gives the character the Bald and Earless traits if the user wishes for the character to have no hair/ears visible and have it be a full bone head. 
If the user does wish to have hair or ears on the character and for the face itself to be bone instead of the whole head, they may do so as long as at least 50% of the visible head is made of bone.
Those with this trait can have the bone be crystalline or metallic without the need to use any additional traits but still must be skull shaped.**
No blood can be present on this bone unless used in conjunction with the Dripping Blood trait. 

**Note; the bone cannot be made of elements/galaxy as they would simply fall under the standard Galactic/Elemental traits
