Firstly, it's open-source. That means that all code associated with the project is freely available (it's right here!) and you're welcome to download, modify, recompile, and make changes to it as you wish. In fact, there have already been a few forks of the project that added new items, abilities, bosses, and other such things. Veloren is also released under GPL v3, a license that pretty much ensures that the code will always be open-source, meaning that anybody can take the existing code and remix it, mod it, or otherwise build upon it.
