I was interested in doing some Salamanders and was wondering what is the reason for the skin being jet black and them having burning red eyes? I have read that it was because of "a reaction between their unique genetics and the high levels of radiation" - Space Marines Codex (5th Ed. Pg 26), but people tell me otherwise that they are African/once were African. I like the Salamanders regardless, but when you think of a whole chapter, you would think of them to have a blend of all races/ethnicity's. Wouldn't they just be jet black because of the heat and radiation from their planet, causing one of their implant organs to start pumping melanin, turning the person jet black? So what are they? And what are these "unique" genetics?
Thanks for reading,
