Oyunili - Bloodlings

Not many people are aware that bloodlings exists. They came through the Void with their Alpha masters and don't get seen outside of their masters' homes.
The reason for that is that bloodlings have an unique gift. They poses the ability to adapt the physical appearance of a humanoid who's blood they have ingested, with the exception of the goliath race.
They don't often show their true form to anybody, but tradition dictated that they have to be in their natural forms when in the presence of an Alpha, unless other instruction is given.
It is commonly accepted that the above rule doesn't apply in public, as Alphas do not like to share information about their servants. Some more ... more aggressive ... alphas do not treat their bloodlings well and the Alphas don't want the Lumin elves to start caring for them the way they did for the humans.
  An average Alpha household has one to two bloodlings. Some of the families have three. If a bloodling's master dies, their family members usually distribute the deceased bloodlings among themselves, or sell them to other Alphas.
Whenever an alpha is in need of a new bloodling, they can either request one from the Void slavers, or buy one from an Alpha that doesn't want or need one anymore.
