Suggestion: Make the portal require shroom lights or something? Glowstone portal is cool but it's already been used. Another reason is because since Hydos is working on fabric <--> forge, it is going to enable significant compat. I guess it could also serve as preparation?(edited)
It's not a bad idea. I'm not sure whether we'd want to change the portal, but it's something to think about. Maybe a config option, or an automatic compatibility thing perhaps?
