Special Encounters: Tower of the Re-Animator

I'm about to start keying the sandbox following Blair's advice, so I decided to write down a list of "Special Encounters" I can use when the dice tell me to do so. ("[...] when the dice tell me to do so"?! GOD I HEAR VOICES IN MY HEAD!). I want these encounters to be kind of jokes and filled with many quotes from pop/geek culture to maximize the fun of playing them. The following is a clear example of this.

The Tower of the Re-Animator
Dr. Herbert East was a fairly successful physician in Mizara around eight hundred years ago. Although, he was always insanely attracted to death and immortality, and so conducted many strange experiments in the processes of re-animating dead bodies. When, due to the failure of one of his experiments, he unleashed a small scale zombie holocaust, the citizens of Mizara expelled him from the city. For days he wandered aimlessly through the wastelands of Yaqqothl, until he finally found an abandoned tower. Settled here, he discovered that the tower was home to a vast library of forgotten and prohibited tomes. Here Herbert uncovered the secrets of necromancy, conducting thousands of experiments on unfortunate travelers who were passing near the tower. Nowadays Herbert is still the lord of the tower, having found a powerful spell that allows him to replace his dying organs with new ones, granting him virtual immortality.
