The Rise of Hollowfall Evermoor : Season 1 Episode 21

Sorsha is fated to release the third founder, but she is still protected by her love for Seb. So the founders summon Hollowfall, a small village which rises every 600 years. It is said that 'the champion' is chosen to visit Hollowfall and come back to Evermoor, but Tara, Otto and Sorsha soon realise it's a one way trip and the founders have rigged the results so that Seb will leave, leaving Sorsha to be taken as host.
