Arthur & Merlin plot
"The Legend Begins"
The youthful Myrrdin speaks out against the reign of the king and as a result he is chosen as a sacrifice. Young Arthfael volunteers to perform the sacrifice but instead lets Myrrdin flee and go into hiding. Arthfael grows up to be a warrior in the King's army, but is banished from the kingdom when he defies his assistant, the druid Aberthol. Guided by his magical sword, Arthfael sets out in search of Myrrdin with the intention of defeating the evil druid's dark magic, enabling him to free the kingdom from war and suffering.
