In the next episode of fantasy drama Merlin‘s fourth series, the mysterious Julius Borden arrives in Camelot with news of a magical secret that threatens to change the landscape of the kingdom for ever.

He has located the final part of the key to the tomb of Ashkanar – an ancient mausoleum which holds a very special treasure: the last remaining dragon’s egg.

Aithusa airs at 8.15pm on Saturday 22nd October on BBC One. In the meantime, here are some teasing lines of dialogue from the episode…

» ‘It is not worth anyone’s life.’

» ‘The legends tell a tale only the druids know.’

» ‘What can I say, execution didn’t really appeal to me.’

» ‘This is your chance, Merlin; your chance to escape your meaningless life!’

» ‘Don’t tell me; it was too salty.’

» ‘It’s cost me twenty years of mine!’

» ‘Are you a good liar, Merlin?’

» ‘Dragons cannot be used like that!’

» ‘Is that another word you made up?’

» ‘I am a dragon lord; it is my sacred duty to protect the last of the dragons.’
