WMG: Fireball

Fireball is set in The Matrix
Or better it is set outside of it in the first 'Robotcity' the robots had created. Not only that but Gedächtnis mentions a war that had happened years ago, a battle against humanity. Gedächtnis also mentioned that the city is surrounded by a desert, the city that the robots had built in Animatrix was located in Saudi Arabias Rub' al Khali, which is a large desert.

Drossel is named after Drosselmeyer.
I suppose this is just a shot in the dark, but come on! A famous character who develops a lifelike puppet. It can't be a coincidence, can it?
