Basically I'm trying to send from the start place in a universe to another place data. I can't use datastore because I have no way of transferring the key, and if I choose a players ID to use as the key it doesn't work for what I'm doing. Any ideas on a key that I could get in both servers, or a way to send across the key?
You can use datastore. Simply set a key of "interserverdata" or something for both servers to watch. I hope this helped!
