Giant-Kin result from the interbreeding of giants and humans. It is a painful process and the human mother often dies during or before the childbirth. However it is possible for a male human to sire with a female giant, but this is rare.
The resulting giant-kin children can successfully breed amongst themselves and with humans, the progeny will be giant-kin. It should be noted that giant-kin vary in height considerably, first born from a giant parent will range up to 10' in height, while the more normal ongoing size for second generation will be in the 7-8' range.
Firstborn giant-kin often have similar resistances and abilities to their giant parent, but it is rare for second generation to manifest these.
The giant-kin population in Bjurholm are descended from Ice giants and what was the local human population of sea raiders.
