The Once and Future King
This idea been bouncing around my head for a while now so I thought I'll get everyone's input as I try to flesh it out.
Its a story arc which involves the reutrn of King Arthur (possibly as the PC Captain of the ship).
The first scenario is one I titled the Cyrstal Cave where the PCs find Merlin in suspended animation in the crystal cave Nimue stuck him in all those centuries ago.
The return of Merlin sparks a series of events in which the incarnation of all the great heroes and villans begin to appear but with distorted memories of who they are and their purpose.
The next scenario is called the Sword in the Stone where the PCs set off in search of the Sword Excalibur which would rectify many of the problems brought about by the reutrn of Merlin and others.
The Grail Quest is a mutli-parter in which the PCs are tested by blood, fire, water, earth and air before they gain the ultimate prize the Holy Grail.
The return of the Holy Grail also leads to the Fields of Camlann when a apocalyptic war breaks out and the PCs are the only ones who can stop it but in the end, can the Captain avoid his fate, dying on the Field of Camlann.
Arise, arise, Riders of Theoden!
Fell deed awake: fire and slaughter!
Spear shall be shaken, shields be splintered,
a sword-day, a red-day, ere the sun rises!
Ride now, ride now! Ride to Gondor!
