Maenad

Maenads are wild, but very intelligent and peaceful nymphs that are serve their loyalty to Aslan in the world of Narnia. These beautiful pale-birch nymphs are described to be madcap young girls with black hair. They are physically identical to human girls, and are not proper nymphs, such as Dryads and Naiads. Maenads mainly appear in Narnia since they were loyal followers to Bacchus.

Prince Caspian
Maenads first appeared in the fourth book of C.S Lewis, Prince Caspian, where they came out of black mist of the trees very happily and wildly after hearing Aslan's roar. The Maenads gathered around Aslan, Lucy, and Susan where they were bowing, curtsying, and waving their beautiful thin arms at them. maenads were very happy to see Aslan until he managed to restore the land of Narnia during the Narnian Revolution. Maenads were running up their legs on the Tree People and circling round their necks. Lucy saw that the Maenads were carrying grapes around the a Silenus who was riding a large donkey. After the Second Battle of Beruna was about to end, Bacchus and the Maenads traveled with Aslan, Lucy, and Susan when they were leaping, rushing, and doing somersaults to the bridge of Beruna. Arrving at the spot of bridge when they met the water god, they managed to destroy the bridge in order to stop the Telmarines from retreating by the Old Narnians. Two of the Maenads join hands with Gwendolen, who whirl her around in a merry dance and take some her clothes that she was wearing.

BBC Portrayal
Since Maenads didn't appear in the 2008 Disney Film, they only appeared in the BBC adaption. They are portrayed to be human-like natives where they carried spears, swords, and bows and arrows and serving their purpose with the Old Narnians. Maenads were first present in the bonfire when they were dancing around the fire with the talking beasts, and the fauns and some of them that were playing the drums. Two of them took Caspian X to join the dancing around the fire. Maenads took place in the Second Battle of Beruna where they fought against King Miraz and the Telmarine army.
