according to the official record. according to my alternative history camels were indigenous worldwide. camelus knoblochi had a north american version, or perhaps even the same camel as was indigenous to the North. Mark my words within the next decade or so an extinct North American indigenous camel will be found and when you see it, remember this. one thing people forget is that the middle east and the sahara and steppe used to be densely forested. deserts are all manmade due to overfarming and overgrazing. there are no natural deserts. meaning the camel is not really a desert animal, but we are so used to seeing them in that context that we assume they are. Kemet (the original name of Egypt) referred to the black soil of Egypt, the terra preta like in the Amazon, something which is only possible with dense forests. by the way, when someone says black magic or dark magic, they are referring to Kemet which refers to dark soil, ie. fertile. So when someone says dark magic or blackmagic, they actually mean fertile soil magic.
