History
Ruling over the South of Oz as the Good Witch, Glinda is friends with Zelena and gifted an emerald pendant to help control her magic. For reasons unknown, she is later banished to the Enchanted Forest and begins living in the woods, south of Rumplestiltskin's castle, hidden in a pocket dimension of ice and snow, which only the pure of heart may enter through. Sensing the incoming presence of Snow White and Prince Charming crossing into her realm, Glinda makes herself known to them. When Snow White asks for Regina's whereabouts since she was just with them, Glinda states that the Queen didn't meet the qualifications needed for entering through the door. The banished Good Witch briefly explains her past friendship with Zelena and tells them the Wicked Witch's greatest weakness is light magic. Recalling that her own daughter, Emma, is a product of the strongest magic of all—true love, Snow White believes she may able to defeat Zelena. Glinda agrees with this sentiment; further prompting Snow White to go through with casting another Dark Curse to send everyone back to Storybrooke.
