They could be kings of Sweden (such as Yngvi and Jorund), Denmark or a Norwegian kingdom, and sons of kings, such as Refil, but they could also be men "without roof" like Hjörvard the Ylfing.[clarification needed]
In the Norse sagas, such men without roof could be so powerful that they could subdue a country and make themselves kings. Two examples are Sölve who killed the Swedish king Östen, and Haki who killed the Swedish king Hugleik. However, in both cases they ultimately lost due to lack of popular support.
