Nevar is mysterious figure who wears a black-hooded cloak and an iron mask, introduced in the second series and whose name is the reverse of Raven.
The forging of the six symbols long ago, which brought sorcery back to Raven's land, also brought the scourge of Nevar who attempts to spread darkness once more. He wears a silver mask and and a black cloak. 'Nevar' is 'Raven' backwards. He appears in every series of 'Raven' apart from series 1.
All that can be seen of Nevar's true form is his eyes, which have red irises and red-pink, scorched skin around them. Nevar is described as "the enemy of all that is good and true" by his arch-enemy Raven, and is responsible for the demons featuring heavily in the warrior's tasks in an attempt to impede their progress. He is often seen watching the warriors' progress in his castle and only appears in person at The Last Stand as Guardian of the Portal, where he does his best to stop the remaining warriors from winning.
In Raven: The Island, Nevar's story was relayed by Princess Erina to Haryad. At that time, he had ruled the Island of Alaunus with his dark magic for four years, making Staffs of Power from the Enchanted Oak to arm his demons, in order to stop the warriors from reaching his fortress. Nevar was once a normal human, no more than an upstart baron with a band of brigands as his followers, and considered no more than an irritation on Alaunus. However, he became twisted and corrupt when he stole the Enchanted Oak and used it to create a Staff of Power for himself; as a result, each time he uses his Staff for evil, half of his remaining life-force is taken away, taking its toll on his mind and his body. His iron mask and his cloak hides his scarred, burnt face, marks given to him from a battle with Raven. Until the third series his mask resembled many small pieces of metal covering his face, before becoming a full metal mask in series four.
In Raven: The Secret Temple, Nevar is thought to have been slain, until the last ten seconds of the show, where he is shown to have survived the temple falling on him
