Running a campaign where the final goal is to find and kill a lich. Problem is, no one actually knows what the main baddie is, and I don't want to go out right and tell the players it's a lich.
Any ideas what signs might point to a lich? I was personally thinking something like dead plant and animal life near the lair, people going missing from the nearby town, maybe missing bodies from the cemetery, but those could point to a lot of things.
What else would point to a lich specifically?
