Loki is in some sources the son of Fárbauti and Laufey, and the brother of Helblindi and Býleistr.By the jötunn Angrboða, Loki is the father of Hel, the wolf Fenrir, and the world serpent Jörmungandr.Loki may be depicted on the Snaptun Stone, the Kirkby Stephen Stone, and the Gosforth Cross.Loki's origins and role in Norse mythology, which some scholars have described as that of a trickster god, have been much debated by scholars.
Hence, it is natural that Loki is the inventor of the fishnet, which consists of loops and knots, and that the word loki (lokke, lokki, loke, luki) is a term for makers of cobwebs: spiders and the like." Though not prominent in the oldest sources, this identity as a "tangler" may be the etymological meaning of Loki's name.
Loki is a shape shifter and in separate incidents he appears in the form of a salmon, a mare, a fly, and possibly an elderly woman named Þökk (Old Norse 'thanks').
Loki's positive relations with the gods end with his role in engineering the death of the god Baldr and Loki is eventually bound by Váli with the entrails of one of his sons.
Loki says that he will go into the feast, and that, before the end of the feast, he will induce quarrelling among the gods, and "mix their mead with malice." Eldir responds that "if shouting and fighting you pour out on" to the gods, "they'll wipe it off on you." Loki then enters the hall, and everyone there falls silent upon noticing him.
Breaking the silence, Loki says that, thirsty, he had come to these halls from a long way away to ask the gods for a drink of "the famous mead." Calling the gods arrogant, Loki asks why they are unable to speak, and demands that they assign him a seat and a place for him at the feast, or tell him to leave.
