Also even if most folks in the country were civilized (not nomads) but there can have been 'warrior communities' based on original nomad/tribal roots. Meaning there were specializations, own culture/customs of each group, and rivalry as well (most cases friendly sort). Including complete male and female ones. The witches/shamans fit the wisewoman role from Aiel culture (albeit in this case there are both wisewomen and wisemen).<br/><br/>I like the names and concepts Kathadon had done with my suggestions for gods; like the idea, sun is both a consort to goddess Zetreya but he is patriarch/tyrannic yet same time god of knowledge and civilization. So their union has a conflict of interest and some of it stems from the goddess of shadows/night having had seduced him into infidelity (true rival of Zetreya, as a said goddess, thrives on chaos/killing whereas Zetreya tries to bring peace). Zetreya is not technically goddess of war, so in sense, Zain is warpriest of hers as arsenal chaplain and thus granted access to blessing/domain which is not normal to hers to grant. She is the goddess of wrath though so in sense would fit she is revered as an aggressive force in the conflict.<br/><br/>Qas'ama would fit as an alien entity, not truly human-looking, and be a genderless entity. In pic instead of sand he/she pours blood from the cup, once blood runs out from the cup the world dies or something cryptic like that. But besides that, he/she is more revered as a force of nature than as a person.<br/><br/>What comes to siblings/half-sibling goddesses, there can be lots of fanwork of possible carnal interaction between the two (hinting for potential unknown god/goddess) or even heretical ideas it's one and same goddess (or even twins). The official story is that one of them is from the official union and the other from a side affair from the sun god.
