Loker or Lokero was a legendary Curonian king mentioned in Gesta Danorum. Exiled Danish prince, Hading and an old rover, Lysir attacked his realm, but were defeated.
The text Gesta Danorum, Book One Lysir and Hadding, being bound thus in the strictest league, declared war against Loker, the tyrant of the Kurlanders. They were defeated; and the old man aforementioned took Hadding, as he fled on horseback, to his own house, and there refreshed him with a certain pleasant draught, telling him that he would find himself quite brisk and sound in body.
