Handmade with intricate detailing this brass greifter medallion is exquisite. Well we thought so, so we made it a keychain. The Norse serpent design comes from the legend of Jormungand. The Midgard Serpent also known as Jormungand, the Midgard serpent, is the child of Loki. It was Odin who threw him into the sea. But the Midgard serpent loved the ocean, and it started to grow tremendously large. And within a short time had the Midgard Serpent grown so huge it encircled all the land. The Midgard Serpent was feared by human and also the Gods. Thor and the Midgard serpent are arch enemies. They will kill each other at Ragnarok. This keychain is made from 100% brass that comes on brass chain with a screw lock carabiner. Besides keeping all your keys safe and in one place you will surely get many many compliments on this dazzling piece.
