Begat of a demon, gifted with second sight and shape-shifting powers, the druid Merlin provides much of the momentum of the Arthurian legend. In the process of retelling the fabled wizard's backstory, playwright-director Ellen Geer has concocted a high fantasy with a strong antiwar flavor. The work's emphasis on meshing threads of pagan philosophy and Christian references -- with a side trip to mythical Atlantis thrown in for good measure -- can cause matters to become a little thematically and dramatically muddled. Yet Geer's brisk and buoyant direction makes excellent use of her atmospheric venue, incorporating a moody electronic ambiance alongside some elegant pageantry, thoughtful fight choreography and enchanting choral interludes. Lead Melora Marshall at times overplays her Merlin with a borderline cartoonish physicality, but it is a performance overall grounded in the epic earnestness and warm humor of Geer's text.
