Room 540 is the vault for the legacy assets. The Chronicle of Felicia book has five volumes. Each book features a new magnificent invention that will improve people’s lives and become an economic pillar for the Centiki Exchange. The Sahara Solar Converter is the invention featured in Centiki: Mirror of the State. The Sahara Converter is the Mirror of the State because it belongs to France.

The Colossal Golden Mushroom was introduced before its invention because it was necessary to make the creation of the State of Felicia possible. The Antarctic republic could not exist without the food and shelter provided by the Colossal Golden Mushroom. The invention follows in Volume 2 of the Chronicle. All the other legacy assets are introduced when their inventions occur.
