Magic Beans

The magic bean is a magical transportation device the Blue Fairy gave to Baelfire in The Return. She told him it would take him to a "land without magic".

History
Baelfire was becoming increasingly worried about Rumplestiltskin, his father, because of how his Dark One powers were making him more and more evil. He struck a deal with his father; if he could find a way for him to safely give up his powers, Rumplestiltskin would have to do it.

He spoke to his friend, Morraine about his dilemma, and she suggested he call upon the Reul Ghorm, who has the most powerful magic there is in Fairytale Land. From there, Baelfire met the Blue Fairy and asked for her help. While there was no way to turn his father back into the man he used to be, she could bring both Baelfire and Rumplestiltskin into another world that exists without magic. The Blue Fairy gave him the last magic bean known to exist and told him to follow wherever it would lead him.

Later, Baelfire greeted Rumplestiltskin with the news of having found a way for him to be rid of his powers. He led his father outside and threw the bean onto the ground. It glowed blue and transformed into a large green sunction portal. Baelfire urged his father to go with him, but Rumplestiltskin backed out of the deal and watched his son disappear into the portal without him.

After Baelfire was gone, Rumplestiltskin realized his mistake and called for the Blue Fairy. She explained that there was no way to get to "a land without magic" anymore. But, after much probing, Rumplestiltskin found out the only other way was to use a create a curse is by sacrificing his homeland (Fairytale Land); a feat the Blue Fairy believed he could never accomplish. He vowed to do whatever it takes as long as he could get to his son.
