Your initial topic is a starting point for your investigation, but it's not set in stone. It's fine for your topic to change in response to what you're finding in your research. In fact, modifying your topic as needed is an essential part of the research process.
This video from NC State describes how doing research can help with choosing and refining a research topic:
Our Credo Reference database has a mind map tool that might help you brainstorm topic ideas.
Entering a word or phrase related to a topic of interest into the search box will produce a Mind Map for your topic which can give you suggestions for related concepts and ideas. You can click any of the words or phrases on the map, and see a new map about that concept.
