a question you might ask "how are you free?" the long answer is, digging past steel wall with the thickness of a planet with just your claws and time. short answer, many epochs of work almost to the point of madness. also keep in mind the wall was regenerating if no damage was done with in a certain time period. that is not worst part, leaving the multiverse you came from will try to destroyed every thing below a standard of universal destruction. I was lucky because of the relic was barely at that standard when I first left my home multiverse. I also didn't know the standard of my multiverse is one of rare dense multiverse. it was mined clean so fast that most travelers don't have time to set up base before it was gone. the way of putting it is getting the news late while the locals got it very early.
