Chao Island Info Center

Welcome to the Chao Island Info Center! Here you will find a full guide on Chao and how to interact with them. This website also is home to the Chao Encyclopedia - a Chao Wiki which is an in-depth knowledge base for all your Chao needs - like Wikipedia, it can also be edited by members of Chao Island themselves for the latest information!

We have worked hard to get as much factual information as possible about Chao. Use the sidebar / mobile menu to select the topic you want to read about. If you have any suggestions or corrections, please feel free to post a topic on our message boards! If you would like to contribute, please contact us and we will be happy to update the website.
