Hermod rode Sleipnir over the gates of Hel to the throne of Hel herself to offer ransom for the return of Baldr. What price did Hel demand for Baldrs return?

Hel demanded that every creature, living and dead, weep for Baldr in order for him to be returned to the living. This condition was meant to ensure that no one harbored ill will or grief towards him, emphasizing the depth of Baldr's impact on all beings. Ultimately, only one being, the giantess Thok, refused to weep, sealing Baldr's fate in Hel.
