Alberich
In German heroic legend, Alberich (German: [ˈalbəʁɪç]) is a dwarf. He features most prominently in the poems Nibelungenlied and Ortnit. He also features in the Old Norse collection of German legends called the Thidreksaga under the name Alfrikr. His name consists of the elements alb ("elf") and ric "power" or "ruler". It is equivalent to the Old French Alberon or Auberon, from which the English Oberon is derived, and is the source of the Norman French derivation Aubry.
The name was later used for a character in Richard Wagner's opera cycle Der Ring des Nibelungen.
