Can someone explain thoroughly what rights you get if you create a server on the graal editor. For example does Stefan get complete control over it and eurocenter gets all the income? Also do any of you know any ways to start off a new graal type game without voiding copyright?  

Your paying to use their product.

All files uploaded to your server belongs to graalonline there after.
Your server won't be making a profit unless it's on a idevice. Therefore Eurocenter is putting the options for players to purchase packs such as on classic/era that has nothing to do with you. Simple

By not putting things in the game that would violate copyright laws.

* All files uploaded to a server immediately become the property of GraalOnline. Usage rights are granted to the server on which the files were uploaded. Consequently staff may not remove any of their work from the server upon quitting or otherwise leaving their position.

The rule is mostly for classic/hosted servers which when a staff member is removed, sometimes they want their work removed. If you are the owner of your playerworld, you "own" the content and can remove it at any time.

Nothing belongs to Graal than even when you can just use them on Graal than. As long as you won´t upload it, it´s yours.
