The Ruins of Shar-Lin Part 9

The Library of Shar-Lin was a small retreat for scholars from Janesh.  They studied geology, botany, history, local magic and even the interactions of different groups of people.  The last Headmaster of Shar-Lin was a man named Kang.  He was happy, for the most part, but wanted more time to finish his study of the world.  So he researched a way to do so, coming eventually to the need to become a lich.  But he didn't want to rot away to a skeleton so he studied more, and found if he sacrificed other people, as well as a few other things, he would keep his body for the ages as well.  So he sacrificed all those scholars at the Library and shut the building up so he could continue studying through the ages.  Over the centuries he's gone slightly mad and can't be reasoned with.
