Sword Of The Stone
Merlin loses the Battle of Stonehenge and hurries to a mortally wounded Arthur in the caves below the Tor in Glastonbury. More
Using his magic powers, Merlin repels attack after attack from the Morrigan's army. When Arthur is defeated at Avebury Henge, the power of the stones wanes and Merlin is no longer able to pull enough power from the ley lines to hold Stonehenge.
When Sir Gwain arrives with news Arthur is seriously wounded and being taken to the Tor at Glastonbury, Merlin hurries to meet his king, knowing Stonehenge will soon fall.
