Consult an IP lawyer. George Lucas had a team that kept his trademarks viable—by suing everyone who attempted to use his IPs without permission and payment. Disney, who now owns the Star Wars’ IPs, are even better known for suing everyone and their brother to protect their IPs. Eventually someone will find the worlds built on Star Wars, and other trademarked properties, and Storium will disappear as all of the company’s money will be spent defending themselves in court. You have a brilliant company, and I would greatly miss it, if it went down the legal rabbit hole because Narrators were building on someone else’s IP. In my first day browsing the worlds needing players, I found 3 legal disasters waiting to happen.
