Heimdall

Heimdall (Old Norse: Heimdallr, classically glossed as 'World-Shiner' or 'World-Pillar') is the vigilant guardian of Asgard, the sworn protector of the rainbow bridge Bifröst, and the mythological progenitor of the three social classes of mankind in Norse mythology. Renowned in eddic tradition as 'the whitest of the Aesir' (hvítastr ása) on account of his untarnished brightness and upright character, Heimdall resides within his celestial fortress Himinbjörg ('The Sky Cliffs'), situated at the frontier where the incandescent bridge touches the perimeter of the gods' realm. His physical senses transcend all mortal limitations: he requires less slumber than a bird, discerns shapes across a hundred leagues by night as clearly as by day, and hears the grass sprouting from the earth and the wool lengthening on sheep. Entrusted with the sonorous horn Gjallarhorn, which rests beside the root of the world tree Yggdrasil, Heimdall is tasked with sounding the piercing blast that will summon the gods and Einherjar when the monstrous armies advance at Ragnarök. In the civilizing poem Rígsþula, he wanders through Midgard under the guise of Rígr, visiting three distinct households to father the foundational ancestors of the medieval Scandinavian social order: the thralls (Þræll), the free farmers and craftsmen (Karl), and the noble lords and monarchs (Jarl). His cosmological adversary is the shape-shifter Loki: after pursuing Loki to the reef of Singasteinn to recover Freyja's stolen necklace Brísingamen, Heimdall will engage Loki in single combat upon the plain of Vigrid during the twilight of the gods, a duel in which both fall mutually slain.
