Sörla saga sterka

Sörla saga sterka is a legendary saga which was written in the 14th or 15th century.

It is a sequel to Hálfdanar saga Brönufóstra and like its prequel one of its locales is England, which is a vassal to Sweden. Sörli the Strong is a son of the king of Oppland, and is at feud with Halfdan Brana's Foster Son (now king of Sweden). After some adventures in Africa, which greatly resemble Halfdan's exploits in Helluland, Sörli encounters Halfdan, kills him, and takes his ship. Halfdan's son Högni (of the Hjaðningavíg) fights against him but later they become allies.

Much of the story is presented in a similar form in the midsection of Sörla þáttr.
