Skírnir

Skírnir is the servant who does the thing his master cannot. When Frey, lovesick and silent, pined for the giant-maid Gerð whom he had glimpsed from Odin's high seat, it was his faithful messenger Skírnir who was sent to win her — given Frey's own horse and his own sword to do it. Skírnir rode through fire to the giant's hall and laid Frey's suit before Gerð, and when gifts of golden apples and the ring Draupnir failed to move her, he turned to threats and at last to a fearful curse-staff carved with runes of madness, barrenness, and endless longing, until the maiden yielded. He is the agent of the gods' will, and the same trusted go-between the Æsir send down to the dwarves to fetch the fetter Gleipnir. Skírnir is loyalty as instrument — the one who carries out the desires and the necessities the great ones cannot stoop to themselves, and pays the moral price of the means.
