+    Many moons ago, an evil nine-tailed kitsune, a fearsome fox god, ruled the
+    land.
+
+    It had many powers — the ability to shape shift, turn invisible, control
+    the elements. Its powers came from its majestic tails and the kitsune
+    guarded them ferociously. If any fox attained eight tails, it would battle
+    the kitsune for domination of the celestial world. To prevent this, the
+    kitsune stole the tails of all the foxes it encountered.
+
+    The evil kitsune challenged every fox to a haiku contest. But the
+    competition was not fair, and the kitsune cheated every time. When it
+    defeated the poor fox, it stole its tail and threw it to the four winds.
+
+    The kitsune stole your tail. Now it’s time to get it back.
