Dafne Keen, Saara Chaudry land role in ‘Percy Jackson’ season three

Dafne Keen and Saara Chaudry set to star in major roles for Percy Jackson and the Olympians season three.

Percy Jackson and the Olympians series is based on the Rick Riordan book series of the same name.

As per Varity, Keen will star as Artemis, the Greek goddess of the hunt and the moon, meanwhile, Chaudry will play Zoë Nightshade, one of Artemis' lieutenants, in the third instalment.

The official description for Artemis reads, "She prefers the freedom of the outdoors to the politics and formality of Olympus. Her immortal Hunters are her constant companions, and she has little contact with mortals, making her a bit out of touch with modern human culture. She is regal and an honourable fighter who will stand up to grave challenges."

Nightshade is said to be "Loyal Lieutenant to Artemis and first among the immortal Hunters, Zoë Nightshade has been at Artemis’s side for more than 2,000 years. She is a strong warrior and sometimes overly serious in ways that amuse the demigods, but she is also a crucial quest member, willing to strive and sacrifice for the good of all."

The TV series was renewed for season three ahead of season two premiere, which is set to release on December 10.

Season two will be based on the second book in the series titled The Sea of Monsters.

It will follow the events after Camp Half-Blood’s protective border is breached, where Percy will embark on a journey into the Sea of Monsters to save Grover and find the one thing that can save Camp Half-Blood: the Golden Fleece.
