William Shakespeare's A Midsummer Night's Dream is comprised of a few interlocking plotlines, especially the tangled romantic tale of Hermia, Helena, Lysander, and Demetrius, and the conflict between the pixie lord Oberon and his sovereign Titania. Associating these two storylines is Puck Oberon's naughty pixie entertainer, who drives a significant part of the activity of the play. The casing story of Theseus' union with Hippolyta in Athens is significant, as its precision gives a differentiation to the turbulent woodland where enchantment rules and the normal is continually undermined.
