The journey had been long and perilous, but she stood tall as she came upon the place where she had the best chance to call to Heimdall... should he still be alive. There was a cliff, with a wide plateau before the precipice. "Heimd-" she breathed, "Heimdall, I call on thee! Bring forth the Bifröst!"

Heimdall having been honestly surprised by the sudden appearance of Sif (who'd been presumed dead in the battle of Ragnarok). "My lady," she stood before him in his personal conservatory, but only for a moment. The dark man rushed to keep her aloft, then held her in his arms. His mind reached out to Thor and he bid the king to come to his side as he began the trek down the Bifröst bridge toward the palace.
