Well, it actually has 3 modes. You can use the third (Legends Mode) to see the entire entity history of your world.
Because it roughly simulates thousands of years of activity and tracks them, you can read about a Human Necromancer, the books he wrote, and his disciples. You can follow the dwarf that killed him, see that he gave up being a poet after his wife and child were killed by Zombax Warfbringer, the bronze colossus, and joined the army before cutting his way through zombies into the tower. Of course, he looted books (his past as a poet) and read them - giving him the secrets of life and death! So whoops he's now a necromancer. Oh well!
