Mixed Races

There is a large assortment of people that do not belong to one of the 3 main races (Man, Dwarf, Elf). They vary in appearance, and some are quite rare. The ones listed below are a definite class of 'Secondary Races', but further down the line (in the far future) I believe that all races became one, due to millenia of interbreeding. The result of this is the Human we know today.
 * Atwarven: A usually female Man and male Dwarf. Always Male.
 * Sage (Half-Elf): A Man and an Elf. Male or Female.
 * Atwarven Sage: An Atwarven and a Sage. Always Male.
 * Secondary Atwarven: An Atwarven Sage and a Dwarf. Always Male.
 * Thidar: A very strong, tall man. From an Atwarven Sage and a Man.
 * Secondary Sage: An Atwarven Sage and an Elf.

Parts
How much of each Main Race someone from a Secondary Race is made up of. For instance, An Atwarven Sage is 2 Parts man, 1 part Dwarf, 1 part Elf.
