Lohse is a human, should be chosen by Rhalic instead of Amadia, yes, she's a mystic, but still when I play as her, in the Ancient temple activating Rhalic's pillar, she comments, that she used to pray to him, when she was younger. But also by playing as her, Rhalic won't ever speak to her much, because of that thing inside her, it's demonstrated in the Arena of One, when he wants Lohse to yeld to him and she asks, why he didn't speak to her earlier, he responds because of that demon, now it's quiet, so he has the chance. So she's a champion of some other "deity", Adramahlihk, in fact. XD
About the champions of the other two gods, since they aren't playable race, we can only assume, that there are an Impish and Orcish Godwoken somewhere (maybe even didn't get captured and shipped to Fort Joy). Towards the end it doesn't really matter much, most Godwoken are dead by now.
