The Snowy Hart Family possesses a unique system of its own.
Their system is based on the inheritance of bloodlines, and even if outsiders understand the principles, they cannot surreptitiously learn it.
Hence, for children born into the Snowy Hart family, the amount of family bloodline inherited becomes the fundamental criterion for determining their future family status.
In the Wester Kingdom, it is well-known that the family characteristic of the Snowy Hart Family is white hair and emerald eyes.
From the successive Snowy Hart Lords to all the strong people within the family, everyone shares this characteristic.
Therefore, whether one possesses white hair and emerald eyes is the most basic element to gauge how much of the family bloodline a newborn of the Snowy Hart Family has inherited.
For infants who possess neither white hair nor emerald eyes, they would be abandoned before they come of age.
