Hey William, since UM is your invention, can you tell me about the history of Pitover?

Piltover was discovered by a group of explorers and their engineers on a test flight of an air ship. They settled down on the continent in the sky to work on their projects in peace. Over time, word of that land spread and more and more, engineers, scholars, and even mages migrated there. Now, Piltover is the magical and technological capital of the world. It is also home to the leaders in the field of magiteck. 

...That's all. The rest is up to you.

Or you can change it all, I suppose.
