What’s your favorite primordial deity? Mine is Tiamat.
Gotta be Auðumla – the magic cow who formed from the ice of the primordial void at the beginning of time according to the Gylfaginning, the section of the Prose Edda that deals with the creation of the world in Norse mythology. The exact cause-and-effect of events in this text is a bit tricky because it’s not a straightforward narrative; the stories are presented in a question-and-answer format (also: not my field, haven’t formally studied these texts, don’t know how they work). Basically, though, there was a great frozen void, and then there was a cow, and the cow said “let there be milk,” and Ymir, the first of the frost giants, drank the milk, and meanwhile the cow survived by licking the ice, which gradually revealed the first of the Æsir gods, Buri (what he was doing frozen in the ice is anyone’s guess). They don’t make cows like that anymore.
