Maiden

The seven maidens play a strong role in many Zelda games. Originally featured in A Link to the Past, the maidens number 7 in total. They are comparable to the sages.

The Legend of Zelda:A Link to the Past
In A Link to the Past, the seven maidens are captured and imprisoned by Agahnim. He plans to sacrifice them to break the seal binding Ganon.

The Legend of Zelda: Four Swords Adventures
On a stormy night, Princess Zelda and the shrine maidens fear that the reason for these events is that Vaati's seal is weakening. She summons Link and brings him to the castle so he can protect her and the other maidens while they open the portal to the Four Sword Sanctuary. When they do however, a shadowy figure appears from the portal. This figure was Dark Link, who then kidnapped the shrine maidens and sealed them in crystals. Link must then go around Hyrule and free the maidens from Vaati's wrath.
