In some stories, mostly in more recent literary works, the cliche involving princesses and dragons is somehow twisted to create a more exciting or humorous effect. For example, in The Paper Bag Princess , the princess came to realize that her prince was even more obnoxious than the dragon, and refused to go with him, preferring to skip off into the setting sun alone instead. In some versions, the princess may also befriend, tame, personally defeat, or even be turned into a dragon herself. Indeed, there are a few examples when a curse or spell transforms a princess into a dragon or similar creature (. an alligator, giant bird, or fictional reptile species). In such stories, the transformed princess usually aids her sweetheart in a battle against a force of evil. In The Swan Princess , for example, Princess Odette is transformed into a swan , and she helps her lover triumph in a battle against the sorcerer Rothbart, who has the power to transform himself into a hideous beast (a manifestation of a lion , wolf , and bear ).
Sacrificial protection can be conferred on a single beneficiary or on a group of them.  In cases involving a single person, the protection prevents whoever murdered the person who sacrificed their life from physically touching the person saved without experiencing excruciating pain,   and will cause a Killing Curse cast at the saved person by the murderer to rebound.  In cases involving multiple beneficiaries, the extent of the protection is not known, but it seems that it is less than in single-beneficiary cases, so that spells cast by the murderer at those beneficiaries will simply wear off more quickly rather than be reflected back (although it is unknown how that would apply to the Killing Curse). However, the difference in the level of protection could also be attributed to whether or not the victim actually dies since, in the only known case in which sacrificial protection was conferred to a group of people, the intended victim survived. 
The archaeology of the mound is complex, but it appears as if people were sacrificed gradually in a series of episodes. In one episode, 52 malnourished women ages 18 to 23, along with a woman in her 30s, were sacrificed at the same time. In another episode, it appears that 39 men and women were clubbed to death. The mound also holds the remains of two individuals who were buried with 20,000 shell beads. It's possible that some or all of the sacrifices were dedicated to the two individuals. Slide 7 of 51
