Huginn and Munin Ravens Pendant
A pedant with a depiction of Huginn and Muninn Pendant.Odin's Two Raven Necklace
Odin had two raven companions, Huginn and Muninn; the former was in charge of Thought while the latter was in charge of Mind. Odin would send off the ravens at dawn to tour the nine realms and gather information and they would return to him at dusk to whisper all that they had seen and heard during dinner at Valhalla. This is why Odin was known as the Raven God, or Hrafnagud.
