"Topia" is not a commonly recognized word in the English language, and as such it does not have a standard definition. It is possible that the word you are referring to is "utopia," which refers to an imagined place or state of things in which everything is perfect. Alternatively, it could be a combination of the word "top" and the suffix "-ia," in which case it could refer to a place or state of being at the top, or something related to the top. If you provide more context or clarification, I may be able to provide a more accurate response.
