The NPC Lich's Great Escape

I have died 3,261 times since I woke up as a Lich in a dungeon. I don't really remember anything or understand why I'm here - but one thing is for certain: I have to escape. I cannot, CAN-NOT just keep letting these adventurers kill me. I'm sick of it, I'll go mad! I just want to live a quiet life in a cold dark forest somewhere... If only I could get past that invisible wall at the dungeon entrance! UGH! Surely, this is a curse? For some reason, I have the ability to remember after every death - the other undead here are killed and don't remember a single thing after they resurrect. I have to do something, something has to change. Join Vlad the NPC lich, as he escapes a dungeon in a computer game world full of adventurers - the only sentient NPC monster.
