Princess and dragon is a generic premise common to many legends, fairy tales, and chivalric romances. Northrop Frye identified it as a central form of the quest romance. The story involves an upper class woman, generally a princess or similar high-ranking nobility, saved from a dragon, either a literal dragon or a similar danger, by the virtuous hero (see Damsel in distress). She may be the first woman endangered by the peril, or may be the end of a long succession of women who were not of as high birth as she is, nor as fortunate. Normally the princess ends up married to the dragon-slayer.
