Alice's story began when she dropped down the rabbit hole, and landed at the bottom in an ungraceful fashion where the Cheshire Cat was ready to greet her. Alice chased the White Rabbit as soon as she saw him and was able to obtain the Vorpal Blade for the first time.
She was eventually told that the person she was searching for was Mayor Elder, the Mayor of the gnome civilization. From there, she traveled through the Village of the Doomed to Pandemonium.
Dementia was an underground mining city with the platforms and buildings mainly constructed using wood, rock, and stone. The city itself was shaded green and was a fairly small city with very few residents, all of which were known to be males. It also had a few shops and areas where products were made.
Due to the corruption of Wonderland, the waters that used to flow beneath the city turned into deadly green color which was poisonous to Alice.
