Runic songs describe him as a primordial being, sometimes called Old man Kave or Lord of the North. He is linked to Väinämöinen as a father figure or ancestor.

Others describe him as Fiery Tursas who steals hay and burns it, causing a giant oak to grow. Scholars debate whether these names refer to a single entity or multiple distinct beings.

The etymology may also involve contamination between words for giant and thunder.
