Okay, I think I might run into trouble here as I lack the main module dependency.
Is there any way to add it afterwards? I tried to do so through the module settings but it won't let me add anything. :S
I have already made a fair amount of level work, do I have to recreate the module from scratch or can I migrate everything somehow?
While I thought you would be able to add it, what you can do is make a new mod and just copy the files from your old mod into it; it shouldn't have much issue, but take a backup of your mod first.
