You're a Lich and Keep Getting Attacked By Adventurers

You're a powerful lich living in your ominous evil lair, you mostly sit on your throne menacingly all day and occasionally read or ponder your orb, your undead thralls not having much to do most days. But for some reason, adeventurers keep breaking into your fortress and trying to kill you. What will you do? Kill them? Talk to them? Teleport them to the woods? Take over the world? Open a bakery and raise orphans? Up to you.
